Exhaust Engineering: X-Pipes, Y-Pipes, and Boom Tubes

same as as this. I just don't have the uh This is a a replica that I built of the system that was on Jeff Gordon's car when he [clears throat] won the '97 Daytona 500. >> Jeff Gordon turned in the sixth fastest speed last year during first day qualifying and uh Jerry Punch has more from down in the pit area. Well, Bob, as you watch Jeff Gordon get ready to qualify, the wind has picked up. Take a look at the flags up and down pit >> That's the the real one like this is in a museum somewhere, probably back at Hendrick Motorsports. >> Still on the car? >> Yeah, yeah, exactly. And that car is in a museum. >> for Jeff Gordon. He's doing this for someone else. >> Here goes the pass. Gordon making a move on the inside of Earnhardt. Oh, Jeff loses >> [screaming] >> down the back straightaway. Big trouble. Earnhardt out. >> And this is a replica of [clears throat] what I had on Sterling Marlin's car. After after I did this, I then started getting requests to Well, we don't want a split system. We want to have have it all run out one side. And that's when they want to put all their exhaust out the right side of the car to have the weight over on the right side of the car. And then NASCAR later told them, "No, no, you have to put it out the other way because you got to keep the exhaust away from fuel in case during during a pit stop you spill some fuel, you don't want to have a fire." This could go either This could go either way. So, I imagine what I what I imagined is >> [clears throat] >> I I left left home. It was just before Christmas in '96. And when [clears throat] I stayed in Embassy Suites for a night so I could be alone, nobody bothering me, >> [snorts] >> I designed that. And I the way I I imagined it is just like I imagined that this stuff would stretch. And here's my here's my split system like this like this. Imagine taking this and just if this was like rubber, I just stretching it over here. So, that's that's how I did that is is get it in a little bit closer so I have time to bend here. Then we went into into a dual inlet boom tube. Now, this is you asked me a question earlier about if a boom tube could change the sound. In this case, the answer is yes because they would combine the uh merge merge the exhaust right here into one one boom tube kind of like like these systems back here. And then it would go out and it'd have a beautiful just beautiful sound. >> You…
