hi, first post here, and it's a weird one! start off with a bang i guess.anyone know if there are any drawbacks to making my own straight pipe racing exhaust? the car is a 2006 gas turbo model. not for road use, as it would bypass the catalytic converter and muffler and would therefore not pass maryland on-road emissions testing. just a flange and a pipe exiting out the back of the car from the engine. performance mufflers are too expensive coming from europe, and if i'm going for raw unrestricted power it makes more sense to me to just fab up a pipe, though i don't have experience doing exactly that. for switching back to road use, i have 2 stock mufflers that i can bolt back up. constructive advice is appreciated!!~hoov
