Something to think about, if your altered vehicle is involved in an accident and is checked by yours or the other guy's insurance company , they can and will walk right out from any coverage of your vehicle because the vehicle has been altered from "as built and certified". It is getting more difficult to alter vehicles today from the "as built and certified" . Changing tire size, exhaust system, performance chips etc., are coming under high scrutiny accident cases these days.

 

That is one of the reasons I also suggested non-chambered mufflers.

Like I said, listen to some clips from YouTube to see what you can find. And see what they used on their car.
