Couple of Q's 1. Where can you get Pypes H pipes from? I can't see them on their website: http://www.pypesexhaust.com/sys-mustang2.html 2. Who makes catted H pipes for the GT? Sadly in the UK I would not get away without running CATS. Cheers.
ok that makes more sense. Anyone know of any catted H pipes or ones that fit to the standard cats like the Mac Pro Chamber?
MRT makes a catted H pipe. Not sure on the power increase, but have read it gives that deep tone. I know the stock catted H is very restrictive of sound. http://mrt-direct.com/concept/exhaust/2005.php
