Would it hurt to run some type of tubing (like the colored Exhaust tips-(G70334)) but mayber copper or aluminum and make them run out of the tuned pipe to make your own dual exhaust. I was just wondering because I think it would be cool to run exhaust back to the rear or out of the hood of the body. I don't really think it would hurt because it would be about the same as the exhaust tips but longer but just want to make sure.
