MAC is an excellent product, i run their headers and off road H-pipe. MAC also focuses their production almost completely on exhaust products (that's how they started out) so i'm sure they have a good product. Anyway MAC does make an X-pipe and a prochamber, which is somewhere between an X and a H pipe. The downside of the Prochamber is that it does not come w/ cats.
