Evolution of Crossover Pipe Designs

it was like one of those HP books about different types of exhaust crossovers. They they had the H, and then it showed a an interesting system where they had the two pipes parallel. And this is similar to the one that that Borla makes it right now, and it's like like this. Ooh ah, you know, the coolest thing since sliced bread. >> The Z pipe, is that what they call it? >> pipe, yeah. Like, it's not new, folks. It's It's been in a book for probably 50 years. Anyway, so I made some of those. And this is back in the '80s. I was telling a friend about how to make this, and he didn't understand. So he goes to the exhaust shop, and they come and they cross these pipes right together like like like a handrail. No bends there at all. They're just But they're they're just open like that. He said, "I actually like it pretty good." I thought, "Well, that's ridiculous." I thought Then it just like click, lightbulb moment, we've got to put bends there and make it so these are tangentially That was the my scientific name at the time, tangentially siamesed. That's what I called it. Crossover. I didn't call it an X pipe at first. I called it a tangentially siamesed pipe, and I realized that that window and they come back apart. The whole idea here was to
