This is a story/question. Yesterday I put my tanabe 3" exhaust on, and when i went to test the sound quality, it started missing bad halfway down the road. Completely dead cylider, i though i blew a piston. Pulled it in my driveway and looked under the hood. A disconnected spark plug wire. Phew. Took it out again and it starts smoking...i know its just the new exhaust burning off whatever it is they need to burn off. Smells horrible. Like a pop can in a fire. It stopped smoking but it still smells pretty bad. Anyone know how long it stinks like that?
