TEASER: HP Autowerks 1M with Berk Technology Race Exhaust

This exhaust sounds good.

It is a race exhaust so some droning at cruising rpms. The system consists of a replacement resonated midpipe and newly developed axle back race muffler. There is a noticeable gain in power. The midpipe added the most power and the race muffler supplemented.

Enjoy!
