Cantrell Motorsports is the only licensed US dealer for Carnewal GT Mufflers. The Carnewal GT Muffler Modification allows for slightly more power with a better tone, but with no exhaust drone.

The Carnewal GT exhaust is a reworked original exhaust, modified in our workshop.

It looks just like stock on the outside but the internals are changed to a better breathing, less restrictive exhaust. The result is a louder and deeper sound with no resonance. On the cars with Tip gearbox, there is no droning between 2200 and 3000rpm.

This exhaust modification we perform does not cause the check engine light to come on or affect emissions testing in all fifty states.
