its not really restrictive, its just the loop sort of muffles it a little more. Just because its quiet doesnt mean its not flowing better than the stock unit. And pics will follow soon. I just have to clean out my digi camera (600 plus pics on the damn thing)

 

well, i just got mine installed on wednesday, and im very pleased with it. it looks great, and there's a complete difference driving my car with the 2.5" piping (i also removed the cat and am running 1 resonator) it sounds amazing too, no ricey tone, unless im sittin at 8200, lol. my muffler shop around here only charged me 128 bucks (including tax) on the piping, labor, and resonator. not bad at all, 128 + 95 for the muffler = a full exhaust system for around 230 bucks, not bad at all. hopefully i can get some pics and videos up soon. srt, i wanna see yours too, get some pics/videos man!
