Varitune Mufflers for Customizable Sound and Power
BBK's Varitune mufflers are the first of their kind in the aftermarket, featuring a patented internal power valve that offers full adjustability for both sound and horsepower. The muffler's power valve can be adjusted to one of two settings:
- Closed Valve – Blocks exhaust flow and forces it through all three chambers of the muffler, producing a smooth, mellow exhaust sound.
- Open Valve – Allows exhaust flow to take the path of least resistance, creating an aggressive, throaty exhaust note. Simply adjust the valve with a wrench to customize the exhaust to your liking.
High-Flow Tubing for Maximum Exhaust Flow
Designed with 2.75" mandrel bent 304 stainless steel tubing, this exhaust kit delivers unrestricted exhaust flow for maximum power gains. The large diameter tubing reduces backpressure, improving horsepower and torque while enhancing throttle response. Whether you're accelerating on the street or track, this exhaust system ensures peak performance.
