it was a shitty looking exhaust. two small rust color pipes sticking out about 8 inchs. no one with a beefed up motor is going to go to midas muffler and asks for 1 7/8 duel exhaust when i see exhaust like that i think stock motor. i could of been wrong but i don't think so. when he floored it it didn't move out that well. the firebird would of freight trained that camaro if it hooked.
