ok people, sorry to bother wit this question. i've tried searching the forums bout this and i'm gettin some mixed info from it. i'm thinkin bout gettin the stillen exhaust instead of the stromung cuz i don't feel like spending over $500. ok so i hear u just replace ur stock muffler wit the stillen one. but the piping doesn't fit so u have weld it on? is that true? if it is, wouldn't' that be a pain in the ass?
