I'm getting my GT very soon, and once its broken in I'll be doing exhaust ASAP. I'm just trying to figuire out what setup I'll do. I'm thinking X pipe and cutouts right before the mufflers. For the x-pipe, does it eliminate the cats or are the cats still in place? Is there an advantage to buying an xpipe rather then having a muffler house make one themselves and install it?
thanks
