actually, normal celica GTS + removal of stock resonator (the one after the cat but before the exhaust) + aftermarket exhaust = backfiring. i love the sound! its not the loud gunshot backfiring (only sometimes that happens), but more of the quieter popping and gurgling, and when u shift it is good.

that's what I did when the shop installed my N1 exhaust (straight pipe)
