Lethal Performance 2011-2014 Mustang 3.7L V6 2.5" Offroad H-Pipe

Product Review (submitted on May 6, 2015):
install was quick and easy, took about an hour on the lift, everything fit great. tremendous increase in flow was immediately noticeable. be aware, this is going to dramatically increase your exhaust volume if you already have a free flowing mufflers.

Install was done a 2011, procharged 3.7, with GT500 take off mufflers from the axle back.

I added a pair of resonators to "calm it down". after installing the resonators, the tone is even deeper, and much smoother, with no rasp or tinny sounds , way better sounding than it was before removing the cats. very muscular. and when you put your foot into it, it doesn't disappoint. it downright howls once you get into the revs.
the best part- the wife doesn't think it sounds like rice anymore.

great product if you want to improve flow and decrease resistance in your exhaust system.
