Which would go better with my Magnaflow catback: MRT catted H-pipe, or Magnaflow catted X-pipe? What is the horsepower gained from both, and does one sound deeper than the other? TIA

UA2k1GT said:i would recommend getting a Mac Prochamber (what I run) or an X pipe.
The X pipe makes it sound pretty smooth, somewhat exotic sounding, but still recognizable as a mustang.
The Prochamber makes it sound deeper and still very different from your typical flowmasters, but still sounds like a mustang.
An H pipe and magnaflows sounds very deep, but also raspy and unrefined (not a clean sound). IMO it sounds like a beat up truck with rusted out mufflers, doesn't sound like a mustang at all.
UA2k1GT said:yes it's an H pipe, but not a traditional H pipe. Its almost like a cross between an H and an X because the crossover is so large.

UA2k1GT said:Yes it will fit stock headers, just buy the one for stock/shorties, and it will fit to any catback. They only come offroad.

UA2k1GT said:just keep your stock h pipe and at testing time, swap them out.
