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.

You can do that, but keep in mind you will be changing the tuning of the pipe and creating more pressure which may effect engine performance.

We recommend keeping it as stock as possible unless you are confident in changing the tuning of the engine without causing engine failure.

Good luck on your project.
