Ok. Well I was gonna go with the Megan Catback (NA TYPE) and try that out, but I have a friend with a mitsubishi 3000 gt (custom turbo yada yada yada) and he said I should get a warpspeed Y-pipe, Test pipe, and then get straights all the way back then put a nice tip on it. first of all...should I do this or stick with megan racing. 2nd. should I make my car dual exhaust because I think that just looks hott as all, and third...if I did make it dual wouldnt I have to get a new bumper first? or could I some how cut the old one, oh...and one last thing...what do I need to make it dual? or can the guy at the shop just do that?
Thanx.

 

you can easily have a body shop cut the bumper. inl ooking at ants it looks like that is what he did, and it looks really good.

you can get slick and do an undercar muffler after the catalytic. you do a single input dual output muffler and do the dual split from there other wise you have them weld in a section of y and go from there. essentially the under car muffler would eliminate a need for one at the end of the piping

 

whatever you do, don't get rid of the muffler. your car will be loud as sin with a straight through exhaust with no muffler or cat. it will kill your low end too.
