Okay, i already have a Y-pipe, but i was planning on getting a supercharger. Now I have to get a bigger size y-pipe right ? so what am i supposed to do, just toss mine out and get a brand new one ? Please help, thnx !

 

don't toss it out, sell it to me.....

 

This was recently discussed in another thread, you might wanna look for it.

Synopsis: 2.5 (stock) is fine. 3.0 actually lost 1hp cuz it caused turbulence.. no physical proof yet, but .. if you do get a bigger pipe.. youll need bigger cat, bigger exhaust (custom 3in?) .. lots of $.

 

So i dont need to upgrade to a new RT Cat, Apexi W/S exhaust and Cattman Y-pipe. I can keep all my 2.5" sizes ?

Thanks
