Im sure there are 3" exhausts for that car that people make for turbo applications(by this I mean in theory a 3" should work), maybe Jeff or Domination can give you some heads up building one from scratch. Im sure it would quiet it down a bit and you would still have a muffler in the rear thats not there to keep you from gettingpulled over I’ll get some pics, but it’s very, very tight. I’d have to run under/around the rear diff, and it’s going to scrape like a motherfucker if I do that. The original plan was to use the 3.5" from the DSM, and after I got the car together, there was no way it was fitting. As for the look of a “finished” exhaust, I’ll say this. If I get pulled over, it’s going to be because the cop heard the car, not because he saw the muffler 😃 Thanks for the link redneck, but I was trying to find a no crossover vs crossover dyno. The popular consensus is to run a crossover, but no one can tell me what power loss, if any, is had from not using a crossover of any kind. The exhaust is done though. I’m waiting for the high-temp paint to dry, and I’ll grab some pics of everything. --- _[View the full topic](https://forums.speedlife.net/t/anyone-have-dyno-results-of-no-crossover-vs-x-h-pipe/192783)._
