I did my homework/research and decided to go with these for a more affordable approach (even though i wanted to get the dc sports)....i heard good things in terms of hp gains and such on these but i still didn't hear much about how these'll sound...........i also have a magnaflow cat, and muffler waiting to be put on....will these obx's sound a noticable?

 

most of the sound changes based on the resonator and muffler, basically for what i know if you got that 2 1/2 inch header and have 2 1/5 inch all the way through what that does is allow of increased pitch which usually translates to that annoying buzzing sound that you get from fartcan mufflers, but you dont have to worry about that ^_- im sure the header will make it a little louder but your still looking at after that being what changes the sound
