When that yellow 4 car pulled out to qualify for the 1995 Daytona 500, the sound it made with Boyd Butler's "Dr. Gas" exhaust absolutely turned the motorsports world upside down. What would become known as the "x pipe" was now on the public stage and would soon infiltrate the automotive aftermarket. What most DON'T know is HOW Boyd actually did this prior to Daytona '95. Lucky for us he took photos of everything on those snowy February days at the Morgan McClure Motorsports shop in Abingdon VA. At that time these photos would have been top secret. 30 years later we can finally see them! This is the story of how a literal rocket scientist from Utah completely defined a generation of the NASCAR engine soundtrack. We have a video of actual car in our video with Larry McClure back in 2022 as well as a race shop history tour and Ernie Irvan's 1991 Daytona 500 winning cylinder heads.

Boyd Butler, known as \"Dr. Gas,\" recounts the development of a specialized exhaust system that helped Sterling Marlin win the 1995 Daytona 500. After proving a 4.5 horsepower gain, Butler rushed a custom fabrication process in just two days. The system's unique sound and efficiency became a NASCAR staple for over a decade, marking a \"Cinderella story\" of technical innovation and persistence.
But that's the one that won the 95 Daytona 500.
There's a system being built, we'll get to that.
To listen to this four car, you hear him as he goes by, it's a different sound.
They didn't know what it was and we wanted to keep him in suspense.
A gentleman from Salt Lake City, his name was Dr. Gas.
How is it that I would get to be the one to figure that out?
I might have some details that nobody knows.
So you're like a rocket scientist?
Well, actually I was.
You saw that picture upstairs?
What, working on ballistic missiles and stuff in the military?
I worked for Hercules Aerospace.
But this was on February the 6th of 1995.
In December of 1994, I got a call from Larry McClure.
And he says in his southern accent, he says, you make that...
I'm imitating this, maybe I shouldn't.
He says, you make that work on a Winston cup car?
I says, of course.
Two things, I was going to die trying or I was going to make it work.
I made several systems for him to test and they were around.
And they dyno tested them and they found some positive results.
It looked different, but we didn't know what it sounded like.
You couldn't tell with a dyno run.
They never told us what they were, but I'll tell you what we found.
What I saw with my own eyes.
Horsepower we got with the actual race car system
was increased the horsepower by four and a half horsepower.
I sent him these two test systems and he calls back.
He says, I tried to ovalize those and I ruined them.
And I don't know what he was doing, but running over the truck or something like that.
But anyway, they were pretty much just pancaked.
Was this in late 94?
This was in December of 94.
January comes and goes and I get this frantic call from him.
See, I've got the date here is February the 6th.
So is that from your first visit there?
Correct.
Yes.
So two days before that, he calls up and he says,
put every piece of tubing that you can fit in your luggage and get back here right now.
That was on a Saturday.
I was a scuba diver.
So I had two big scuba diving bags, my gear bags.
I fill them completely full of bins, three and a half inch,
because that was what the rules permitted at the time.
That was your maximum size.
I go out to the airport with these bags full of tubing.
And I set them down where you put your bags.
Clank, the ticket agent comes over and he goes, what's in the bags?
And I said, exhaust tubing.
He looks at me like, why in the world would somebody be carrying around
two giant bags full of tubing?
And he asked to see what was inside.
And I, of course, showed them.
And he shook his head and he goes, okay.
So he checks my bags from Salt Lake to Kingsport,
which is the Tri-Cities area, which is near Abingdon, Virginia.
There's no direct flight.
So I had to go to Atlanta and then come back to Kingsport.
Sure enough, the bags arrived.
Thank goodness.
Got a car.
And it was Sunday evening when I made it there.
So I drove.
I had the address and I more or less navigated my way there.
And I walked in the door.
It was locked.
Knocked on the door.
One of the employees that was there from the engine room came and I introduced.
I said, I'm Boyd Butler from Dr. Gas.
And he goes, oh yeah, we've been waiting for you.
He says, come with me.
They usher me in.
It's my first time ever, ever in a NASCAR shop.
You never see anything like it.
We go into the engine room and there's Larry McClure and Runt Pittman.
You can see where the fans for the dyno's up there.
Runt Pittman with his characteristic toothpick.
You ever meet Runt?
No.
Oh, what a shame.
He has his toothpick and he has it.
He can take with his tongue and he can spin it around.
And the more excited he gets, the faster that toothpick spins around.
Anyway, true story.
Larry says, come with me.
So we walked to the other side of the shop.
The lights are all off.
Pitch black.
And he flips on the breakers and you hear this.
It's just like in a movie.
You hear these breakers.
They go clang and all of a sudden the lights go on.
And I'm looking there and here's these two cars right here.
And I'm looking at this.
I just thought, wow, there's more pictures here as we go.
I've got some of the race and things I took in the pits.
We'll get to that.
See, there's a system being built.
We'll get to that.
The cars were not fully decaled.
They were about this condition right here.
There's our system.
Now notice that this is discolored right here and then this is not.
So that's the system from the car that everybody knows.
Correct.
That is the winning system.
It's been dyno tested.
But that's the one that won the 95 Daytona 500.
And that's the backside of Mark Giles right there.
Mark Giles is the person who was responsible for Dr. Gas getting into NASCAR.
He saw our ad in Chevy High Performance.
Showed it to Larry McClure.
And then Larry McClure contacted us.
I watched your interview with Larry.
He said they hadn't heard the car until they got to the track and were surprised to hear it.
I had noticed when we tested in the dyno room that it sounded the way I wanted it to sound.
They didn't say much at the time, but they were just mostly looking at the readouts.
You know, four and a half more horsepower.
Probably too fixated on that.
It could have sounded like a whoopee cushion.
Runt and Larry looked like they were about ready to do the tango.
And Runt's toothpick was just spinning around.
And as we tested that the first time, we're at 460 or so, 461-ish.
And it goes up to 464.
Larry goes, oh gosh, we somehow lost adjustment.
We're out of adjustment.
So he goes out and he measures the barometer, measures the humidity.
And they calibrate the dyno.
And then he says, okay, take that off of there and put the dyno exhaust back on,
which had an H-pipe in it.
460, 461, 460 and a half.
He goes, huh, wow, nothing changed.
So put that Dr. Gas thing back on there.
464.
They were so happy because four and a half horsepower at Daytona is one mile an hour.
So after 500 miles, where's the rest of the field?
Some distance behind you.
So Larry McClure puts his creeper, there he is right there,
puts his creeper on the ground.
He says, go ahead and roll under there.
So my first time seeing a Wilson cup car, I'm underneath it.
And I'm thinking like, really?
I am just some guy from Utah.
And I considered Utah to be the vacuum of motorsports.
How did he just let you waltz in here and start taking pictures of everything?
This is like Area 51 stuff here.
Yeah, this is.
There's Mark right there.
And here's our system right here.
We've just finished fabricating the boom tubes, right?
You see right there.
This is the second system we made.
This system right here actually ran on the Bush Clash car.
I'm not sure how many people even remember the Bush Clash.
The name has changed.
So you had an X-pipe, but you had to figure out how to make it fit into the car
with the truck arm crossmember and all that.
How did you know if you'd be able to make it work
when you showed up there with your duffel bags of stuff?
Well, as I said earlier, I was either going to die trying or it was going to work.
Well, fortunately, it worked.
Was it hard?
There were some challenges there.
Back in the area of the truck arms, we had some near...
And this system, I have an actual picture we'll look at at the shop.
Shows that we kind of wiggled a little bit of a jog
to get around the truck arm brackets that were right in this area right here.
You took all these on the first day you were there?
Or how many days were you actually...
I was there.
I got there Sunday night and I worked Monday and Tuesday night.
And on Tuesday night, the trailers, they loaded both the cars on the transporters
and off they went to Daytona.
So you had like three days to figure this out?
Two.
Just two?
Two and a half, let's say.
I got there in the evening.
So I rolled under the car and I looked at the thing
and then I went back and got a room at a hotel and literally did not sleep.
Just laid there, looked at the ceiling all night long.
I thought, well, I got to do this and shape that and turn there.
So I thought about it all night long.
Monday morning, Mark Giles.
Here's the young and dashing Mark Giles.
Good fabricator.
He comes to work and Larry says,
this guy, Mark Giles, and you are going to make this exhaust system.
I said to him, or one of the guys, I said, I need a couple of things.
I need some big steel plates.
Half inch thick steel plates.
And I need your shop press.
And I need a bag of sand.
And they look at me like, are you some kind of a farm boy?
I said, yeah, this is all we got.
I only got two days.
Get going.
And so a little while later, there comes my bag of sand and my steel plates.
And I, with Mark, we took, there's their do-all.
No, that's not the do-all bandsaw, but they have a bandsaw.
Mark helps me and we, there's Tony.
There's some of the guys right there working on the boom tubes.
Mark helps me.
Oh, there it is.
This is actually the one on the bush clash car.
We trimmed the steel plate.
So just the area that I wanted to trim, I had to do two things.
I had to make a transition to go from three and a half inch round
down to, at the time, we were using two and a half by four oval.
Because when you took the oval down to two and a half inches vertical,
two and a half, and it was just automatically out about four inches.
So we made transitions, which you can see here.
If it wasn't oval, would it not fit under the car?
Correct.
It would scrape.
Well, the car was pretty low.
Anyway, after we finished these, I said to Tony right there, I said, you know, Tony,
I'm concerned about the vibration right here because the outside radius on the tubing
is stretched and the inside radius is compressed.
So the inside radius is really strong and the outside radius of the bends is not.
And if it's going to crack in 500 miles, I don't want it to fall off the car.
So we need to build some reinforcements around that.
So we built a box.
This was accidental genius.
The box caused at the Speedway, when they're down in the garages at Daytona,
when they lift the cars up to work on the cars.
Right next to us was the 16 car of Ted Musk.
Ted Musgrave was the driver.
It was a Roush car.
And on the other side was, I think it was Kyle Petty.
It was a Sabco car.
And so they lift the car up to go get into their work on it.
And immediately, those other two teams, they're right under the car.
And they're just over there.
They're just looking and looking.
And all they see is they see two pipes coming in.
There's a box.
Now the other end of the box, those two corners, they come out.
All week long, people would photograph this car and try to catch us with their pants down
to see if they could determine why this car sounded so different.
So the following week was Rockingham, and they were interviewing Jack Roush.
They said, Jack, do you have any idea what's on the bottom of the four car?
And he says, well, we know it's a box.
So we've been experimenting with them, and we're going to get it figured out.
There's a lot of talk at Daytona about the sound coming from the winning car,
the Daytona 500, that of Sterling Marlins.
So Glenn investigated, what's up with that strange sound?
I've got an exhaust system development program that we've started to go back and see what
impact a little bit of a plenum will have in the collectors forward to the tailpipe.
I think it's pretty obvious that they've added some volume to their exhaust system.
And whether or not they've got a benefit from it is unknown.
But it sure does make it sound different.
Well, it was not a box.
But anyway, that put them off for quite a while.
And then you had these guys, all these Roush dudes, just having their exhaust dumped into
a box.
I don't know how many people were building boxes.
I'd heard on one of your videos where you had Larry on it, and he was saying, we didn't
really know what it was going to sound like until we put the car out on the track.
And then we were shocked because it comes by.
To listen to this four car.
Hear him as he goes by?
Yeah.
That's a good sound.
And everybody else is going.
And during the race with Sterling out front, it was just to my delight.
It was just sit there.
Nominated this race back in 1990, he led 155 laps.
And they're all chasing, chasing Sterling.
And we win the race.
It's like, wow, that was like, right thing, right, right time, right place, right?
Everything.
Cinderella story.
You know, I'm thinking, how on earth would that happen to me?
Living 2000 miles away.
And how is it that I would get to be the one to figure that out?
It's like a miracle.
Just amazing.
Here's a box being starting to go together.
I don't actually have one finished, but during the week of speed weeks at Daytona.
They do a lot of testing and they do tech inspection and things like that.
And so I went down there for that.
The media went absolutely crazy about that.
You've probably seen the ESPN qualifying for the four car.
Yeah.
Had Bob Jenkins and Benny Parsons and Bob Jenkins.
I don't know if he's still alive, but Benny, Benny's passed away.
Nice guy.
Really liked him.
There, Benny gets up and he goes, I wish we could get a microphone down here for you folks
to hear this four car.
And then here you go.
It comes by.
He says, hear that?
And then Bob's going like, it sounds much, much different.
Sounds like an Indy car.
And Jenkins is going, I think it's got a turbocharger on it.
Well, anyway, later they come in the interview.
Oh gosh, what was his name?
A little short guy.
Glover.
Tony Glover.
Yes.
And they said, Tony, it sounds like you've got 180 degree headers on your car.
Well, of course, which were illegal.
And he says, well, I don't know.
Some have been aggravating us about a new driver.
They're calling Nigel Marlin now.
It's just something that the guys in the engine room come up with a little different combination
in the engine, and it seems like it's working pretty well.
It just sounds so different than anything else we've heard today.
We used to hear the old 180 degree headers.
Is it somewhat of a variation from that?
Well, not really.
It's more like 140 degree headers.
But to be honest with you, I think it's a little slower.
But Larian Runt likes the way it sounds.
So I guess we're going to run it.
You're just making up some BS to tell the press.
And so at that, for the 500 on 95, you started up at the front.
And as that race went on, he gradually, under green conditions,
lapped, slowly lapped the entire field, except for about 11 cars.
There was a caution at about lap 185 out of 200.
First four cars just broke away a little bit right now.
And then you got another trial booth.
I have this beautiful picture through that trial, just how close they're running.
The media was going crazy.
Well, is Sterling going to pit and lose track position or not?
Well, he pitted maybe 10 laps previous or 15 laps.
And were you at this race?
I haven't recorded.
I've watched it many times.
Like, were you physically there?
I was physically there.
Yeah, I'll get to that.
Sterling stays out.
And so everybody else does because they don't want to lose track position.
And they're still on the lead lap.
But they're not as fast as Sterling is, except for Dale Earnhardt.
Earnhardt has brand new tires.
Yours are worn.
Can you still beat him?
Well, I don't know.
You know, we were in a no-win situation.
I feel like if we had pitted, he wouldn't have pitted.
And we would have been at the rear in his position.
So, you know, we got 10 laps to go.
We've had a heck of a week down here already.
And you know, whatever happens will just happen.
You've been talking with Ray Everham.
Are you and Gordon going to hook up together in a draft?
Well, our two cars have worked awfully well today together.
And, you know, hopefully they could be a lot of benefit to us.
OK, we'll see which strategy works.
In a move of desperation, Dale Earnhardt comes in.
And they tape the nose of the car and put on new tires.
So, you know, he's got fresh rubber.
And they tape the nose of the car.
And they don't care if that motor goes to lap 201 and then blows up.
No big deal.
But they literally tape the whole nose.
So there's, you know, so they've aerodynamically improved the nose of the car as much as possible.
So the race goes green.
And Dale Earnhardt's in the back.
And he passes one or two cars every lap.
Jeff Gordon just radioed his crew and said Earnhardt has this in the bag.
I'm not so sure.
And with three laps to go, he finally catches up with Sterling.
And the media, the announcers, are saying, well, oh, Sterling's in a bad place.
Because Earnhardt is just going to get a run on him.
Do it down the back straight on the last lap.
And he's going to get him.
Well, amazingly, every time they get to the back straight, Sterling pulls away.
And Dale Earnhardt, with fresh tires in the corners, catches back up.
The only place that really Earnhardt outruns anybody is, like,
up off the number two corner up the back straight.
And that's what you need to run fast.
Because you get a good draft going in.
Make that last deal.
Yep.
Martin third.
See how he catches him.
I think it really gets that momentum up off there.
Then it cures you all the way down the back straight.
So as the race went, last lap, Sterling does the same thing.
Pulls away.
And Earnhardt starts catching up after turns three and four.
But Sterling wins the race.
So now you ask about me.
I'm there.
I'm standing there and going, like, I am literally shaking.
I mean, I could barely stand up.
It's like realizing, I think my life just changed.
It did.
I don't think they were, no matter what they could have done,
they weren't going to catch that car.
Because I know when I, I don't know if I'll even send there or not.
But when I went to go do that video with Larry before that,
I was talking to one of the crew guys.
And he's like, he's like, look, man, let me tell you, like,
when you go in there, Larry's going to say that car ain't sucking air.
But I'm just here.
It was.
But just let him tell you.
Let's let him talk the way he wants to talk.
But I just wanted to tell you that first that
they had an air leak in there.
I sure didn't know about it.
So I didn't ask him about it.
But there's there was something going on with that car.
Now, I don't believe people say that.
Oh, well, the sound was just the the red herring to distract people
from what was really going on.
No, it was maybe part of the bouquet of whatever they were doing.
But it made more power.
Right.
Well, in terms of the physics of it, the engine is an air pump.
And if you increase the differential at the carburetor to the exhaust,
which is ambient, if you can make that difference more,
it's going to it's going to allow more air to enter the motor.
And that's exactly what it does.
And that's why you once you have that air, you can add fuel to it.
And that's why you have a few more horsepower.
It literally improved the efficiency of the motor and the delivery system,
both intake and exhaust.
We're working a little bit better.
So, Larry, the following week, he's on the phone.
He says, Boyd, you know, I helped you get there.
And I'm thinking like, well, I can help you, too.
This is well, I tell you what.
I want to put you under contract for a year to just be my exclusive sole supplier.
Well, I reluctantly agreed and I was compensated some.
I bought a piece of shop equipment with it.
That was about as good as it was.
Anyway, it actually was it was a really smart thing to do,
because I was not in a position to mass produce the product.
But I learned how to do it during that year that I was exclusive with Larry.
So it gave you some time to build your process.
It absolutely did.
I went out and I bought myself.
I looked and looked for presses.
I needed to have a big, big press.
Well, all I could find locally, short of waiting things like for six months to a year to get,
I found a used drawing press that was about 12 feet tall
and had a ram that was about four feet, four feet long.
And the cylinder, of course, it was that long as well.
I bought myself a hydraulic power unit that would run on single phase 220,
because I was doing this in a 20 or 30 by 40 foot
warehouse type shop building that I had in the backyard of my house.
Is that place still standing?
It is.
Can we go see that later?
We can.
Awesome.
It's not too far away.
But my shop, my shop I have now is closer, but it would be nice.
I can take you to all the places where the company was, except for, no, we can do it.
The sound that that four car made in 1995 became the standard soundtrack of every Daytona 500
until 2007.
Formerly numbered three.
All was black and silver until this year.
That was the last time that the Cup Series had exhausts like this.
Almost, he almost squeezed Harvick into the wall and here comes Harvick, the 29.
That race was won by Kevin Harvick in the Shell Pennzoil car.
That 2007 Daytona 500 was one of the most iconic
Daytona 500 moments of the last 30 something years,
right along with the 1995 one with Sterling Marlin and the Dr. Gas system.
It's pretty cool that it worked out that way because Pennzoil is actually a big supporter
of this channel.
As many of you regulars probably know, we've been with them for years.
I don't know what you use for motor oil or anything, but the next time you need to change
some, find out what Pennzoil product is good for your car.
I personally use Ultra Platinum in my stuff.
I use it in my personal race car and the cars we're driving on the street too,
because Ultra Platinum provides engine protection for the lifetime of your vehicle.
It's independently tested, verified.
You can look it up and see for yourself.
It's legit.
But not only that, when you pour it into your engine, you can feel good about doing it too,
because you're supporting these moments.
You're supporting these videos.
You're supporting the stuff that we find interesting in the moments we remember.
It lives on in your car.
I don't think you ever finished how you actually made the thing when you crawled under the car.
I crawled under the car.
By the way, I had a Sharpie in my pocket.
I crawled under the car and I thought, not often anybody gets to be here.
I took my Sharpie out and I autographed the bottom of the car.
I wrote, Dr. Gas was here.
Unfortunately, they raced that car at Talladega and Daytona for two years.
It was heavily crashed.
That was the big wreck where Dale's roof caved in.
It was a humdinger and it destroyed the car.
It also destroyed my pipes.
The pipes that you may have seen that Larry may have put back on the car
were some that he had purchased from us and put together.
I also have replicas down at the shop, which I'll show you, which I made
that are reasonably close to this one that you see right here.
I used to take those to my Dr. Gas, SEMA, and PRI booths where I would put them on display.
Later that year, Jay Signore from IROC contacted me and he says,
I don't really care if your system makes more power or less power.
I want that sound.
I called Larry up and I said, they're not going to do anything with this year.
Is that okay?
He's not happy.
He says, well, okay.
I started making prototypes.
What was Larry's offer like?
Did his first offer blow you away?
He was like, yes.
Did you go back and forth with him?
No, I should have, but I just helped him win a couple of million dollars.
His offer to me was not much.
That's all I'm going to say.
I don't want to get sideways with anyone.
You'll like this.
Daytona 500 where built February 6, 1995.
Three and a half gain, dynoed with race motor, 464 horsepower.
Wow, this should be in the NASCAR Hall of Fame right here.
This is the coolest artifact that I've ever seen.
This is the Busch-class second place, number two system.
There's a four-inch system I built just for the fun of it.
The collectors were three and a half, see right here.
Then I made transitions and I went out and I ovalized four-inch pipe.
That was technically against the rules.
It was illegal because they had a rule specifying three and a half maximum.
Did you take those pictures on the floor outside the McClure shop?
And Larry didn't care that you were walking around with a camera?
No, I just had my little-
Because you were under contract anyway.
You know, this isn't even a digital camera.
It's before digital cameras.
This is with film.
That is so cool.
So I took these pictures.
If I'd had a digital camera, I would have taken a lot more.
There's one of our boxes, I think.
There's boxes there.
Did anybody figure it out before you made one for them?
Nobody.
Who was the first other team that you made one for?
Well, some of the races I went to in 1995, I went to Sears Point.
Darrell Waltrip had called me up probably within a month of the Daytona 500.
And it was Darrell himself.
And he wanted me to sell him an exhaust system.
And I said, I'm sorry, sir, but I'm unable to because I have a legal limitation.
I'm under contract.
And I know about this because I walked in the pits with my little camera.
You saw my pictures.
And I just set it on the ground and reached down and touched the shutter.
And the flash would go off.
And I'd get a picture of the whole bottom of the car, including the pipes.
And they were doing the hand railing system.
But it was just completely orthogonal or 90 degrees.
And there was no bends here.
This came straight.
So you would put a camera on the ground at the racetrack and take pictures.
Oh, I did it all the time.
Underneath people's cars without them knowing.
Just to see how bad they were doing it wrong.
That's hilarious.
For no other reason than just to see.
I want to see how far off they are.
Well, I had a flash.
I just sat down in there.
I'd be like tying my shoelace and just touch the shutter and flash, you know.
Yeah, that's hilarious.
Oh, I have some of the pictures I'll show you.
Oh, yeah, I want to see that.
Here's one on the car.
This is a Brickyard car.
Indianapolis on August the 3rd.
We had a system on that.
We are back live now.
We've got a lot of fast drivers to watch qualify in the next 90.
One, two, third fastest.
Great layout for Jeremy Mayfield in the RCN Wasp Bobby.
So I don't think Sterling has a pole run going here.
But he's going to have himself a good starting position for Saturday's Brickyard
400.
So for all these, were you flying out to Utah or not flying out from Utah?
Do you do this on every single car the whole year?
Not every.
Well, I had an exclusive contract with Larry for the year.
But following that, then I was on the road a lot.
And I racked up the frequent flyer miles.
So for 95, would they just call you say, hey, we need your stuff.
Come out here and build it.
I've done that.
I've actually built racetrack or I mean systems at the racetrack before.
Wow.
At Daytona.
I wound up missing the IROC race one year.
Hearing my own exhaust from underneath the car in the garage area.
So this is a bush system right here.
You see how tight and short that is.
I made some foreign systems for the Spears Motorsports that raced in the truck series.
They're out here mostly on the West Coast and stuff.
This is me.
I'm still learning how to ovalize things.
That's a five liter Mustang system without a cat.
So when you were under contract with McClure,
were you able to sell any street car systems during that time?
So they were your only customer the whole year.
That was right.
And you were not working for government stuff anymore.
You're past your six months of severance pay.
And Larry McClure's not paying you tons of money.
And you're also trying to buy a bunch of equipment to gear up for...
And Larry McClure is not paying me tons of money.
And you have to realize Larry McClure is in business to make a living.
And so his strategy is to save money where he can.
So I don't follow him for that.
I'm just trying to frame what your state of mind was where you were like you had to be...
At the time, yes, I did feel like I was somewhat being taken advantage of
because I couldn't sell them everywhere.
But you know, it's okay.
Because what I did during that year was important and it set me up.
Did you know that what you were doing was gearing up for the big swing after that?
I felt like maybe it was, but...
The origin of the Kodak car, the Daytona, the IROC,
everything came from that exhaust pipe and this car.
That is correct.
If I touch the accelerator on this more than a quarter of an inch,
this motor will spin up to 3500 RPM.
There are two more videos with Dr. Gas coming after this one,
which I will show you some previews of after this what I have to say right here.
Or he didn't explain when I had the camera on.
Prior to his contact being made with Morgan McClure in late 1994
through that Chevy high performance ad,
he had come to Charlotte and visited race teams,
just cold call show up at the front desk,
say, here, I have this product that can help you.
Can I talk to somebody?
No, no, no, no.
Nobody would listen to him.
Nobody.
He literally presented this to almost every single race team down here.
And none of them, none of them will listen to him.
I don't know who needs to hear this,
but that's a lesson to be learned there that he knew he had something
that was valuable, that was different, that was special.
And nobody listened to him, but he did not care.
He kept going and proved them wrong anyway.
And for 15 years in the cup series,
every single car at the Daytona 500 used his exhaust.
And they all told him to screw off before that.
I just think that's, that's an awesome story.
This is, this is Nuro Uno.
When I finally got this all done to about right here, I started the car.
That shop right back here, you can just see one end of it.
That's the birthplace of Dr. Gas.
My neighbors, bless their hearts, I was getting to be too big.
And one of them complained about me to the city.
KBM.
It says KBM 007 on it.
It must be really early KBM.
Yeah, I don't know who that is.
Kyle Busch.
That's Kyle Busch's truck team.
I was wondering what that sound was.
I opened the door.
That's rocking.
It wants to make noise again.
Here we go.
No, that's too much.
These are a few actual systems here that were raised.
And then these are exhibits from the SEMA show and the PRI show.
That's an actual iROC system right there.
Oh really?
And those of you who've been watching the channel for a long time know that
the X-pipe and the McClure car and Dr. Gas and all that, the way that sound is,
that's a real passion project of mine.
And being able to make this video was really something I have been looking forward to doing
for years.
But Boyd lives in Utah.
I'm in North Carolina.
I don't go to Utah for fun or for anything.
I've never been to Utah ever.
And the only reason that this was made possible is I can't afford to fly places to make a video
or two or three videos and come back and break even.
It basically just lets you know how the economics of YouTube works.
Flying just costs way too much money for the corner of YouTube that I'm in.
It doesn't work.
The only reason this was able to happen is because I was already going out there for
Mark Martin's renewal bill, which he helped me out with the flights for.
So at the last minute, I called Boyd and said,
hey, I'm coming to Utah in like a week and a half.
Are you free on this day?
This is the only day I have to make this work.
I can fly into Salt Lake, rent a car, and drive four hours to St.
George, Utah after that to start filming Mark's thing in the morning.
I can fit it all in if we can do it on this day.
And he said, yep, we can do it.
Let's go.
So that's what happened.
So you have Mark Martin to thank for this being done.
I don't know if I ever would have been able to go to Utah to film this if it wasn't for
that coming up.
So I just thought you could enjoy that little tidbit there.
If you want to support the channel, which I hope you do,
because we try to bring you the best stuff we can,
you can go to staplesandautoworks.com.
Find the hat I'm wearing, the shirt I'm wearing, things like that.
We've been a little slow in the merchandise lately with all the house renovations going on.
But if you order something, you will get it at some point.
It might not be two days later.
We're not Amazon, but you're supporting what we're doing.
And that means a lot.
Also, make sure you're subscribed and send this video to a friend,
post it on your Facebook, share it.
Let's get that out there.
I really want to go back to Utah and do more stuff with Boyd,
because having half a day with the guys is not enough
to absorb and ask him all the things that I wanted to.
Just the stories he had of working on these government projects during the Cold War.
And you'll get a little bit of that in the X-Pipe video
that kind of covers his whole career and also his garage.
So yeah, this is a fun one to make for me.
I hope it was just as much fun for you to watch.
I want to know what you thought about it.
Speak up in the comments.
