Ive was wondering what x-pipe i should put in and does it make a diffrience W/O cats

 

It really doesn't matter what brand you use. BBK and MAC are a couple of good ones. You won't be able to feel a difference in power from the catted pipe and the non catted pipe. The non catted pipe will be alot louder though.

 

they all basicaly sound the same, just depends on your catback. bassicaly do you want it stainless or aluminized.
