listen guys....i know that theres a lotta exhaust threads on here and ive been to mustangexhaust.com countless times but i need some opinions here.....i have the stock headers which i plan to leave for the time being, and i have an american thunder catback....i have 2 questions....do u think that the o/r x is close to the loudness of an o/r h, and does anyone here run flowmasters w/ and o/r x pipe and like the tone...cause im sorta leanin towards it a little bit and i want a few other suggestions.....hp is not really a huge concern considering its maybe a 2-3 hp difference....thx for puttin up with yet another few exhaust questions....
