i never knew that people were insanely against dual exauhst. is this a import tip as a standard.. because i have said before i was only into american cars before my celica, and now since i am getting into the import scene this is definitly the first thing to surprise me. even if i lose a little power with the duals using 1 muffler i love the look. and even seeing it on my celica i dont regret doing it. it looks cool to me. but i definitly respect the whole idea of "if it came with one leave it with one" but then agian why does that only apply to the muffler? ive heard of many people changing gt trannies, engine swaps, as well as all kinds of other mods that in essence "change" the look of the celica. but in the end the consensus is that duals are gay.. but the point of this thread was to find a muffler that wouldnt give me a hp loss, not "do you think duals look cool"
