Alright, I was about to buy a 5Zigen fireball, but the price jumped on me suddenly @ modacar, and come to think of it, I am pretty tired of cops harassing me, so I was thinking....would the stock muffler welded up to 2.5 inch piping do me any good? From what I have heard, the stock muffler isnt where MOST of the restriction is in the exhaust system...so if i got some 2.5 inch piping which allowed more flow....and welded up the stock muffler, I could retain my stock look, (although i dont think it will sound stock, but I am guessing that it wouldnt be THAT loud) and the sacrifice of ponies wouldnt be that great. Dont get me wrong, I love a great sounding exhaust, but Im tired of having to watch my ass and shift at 2.5K whenever a cop is within a 4 car radius of me. So what do you guys think? Does it sound like a good idea? Would a really lose that much power with a stock muffler mated to the 2.5 inch piping? Anyone tried this and have anything to say about it?
