How do I adjust the sound and power with the VariTune system?

The VariTune mufflers have a patented adjustable power valve. You can adjust this valve at the rear of the muffler using a wrench to change the exhaust flow. Once you find the sound and performance level you like, a locking nut secures the valve in place.

What material are the VariTune power valves made from?

The patented BBK VariTune power valves are constructed from stainless steel. This ensures they hold up well over time and operate smoothly.

Does this exhaust kit come with everything I need for installation?

Yes, this kit includes all the necessary new hangers, hardware, and clamps for a direct bolt-on installation. It also features BBK VariTune brushed stainless steel tips.
