BBK VariTune Cat-Back Exhaust Systems
BBK's VariTune cat-back exhaust systems feature their VariTune mufflers that have a patented adjustable power valve inside, allowing full adjustment of the exhaust flow through the muffler chambers for great sound and added performance. This adjustment is made at the rear of the muffler with a wrench by either moving the valve in or out. Once you are happy with the level of sound, it is locked in place with the VariTune locking nut. All power valves are made with stainless steel for lasting durability and continued smooth operation. These patented BBK exhaust systems allow you to personalize the power and sound levels of your car 8 to 10 decibels and 10 to 15 hp. The aluminized steel piping with brushed stainless tips allow a direct bolt-on replacement for the restrictive factory system.

BBK VariTune Rear Axle Back Exhaust Systems
BBK VariTune axle back exhaust systems offer full tuning ability. Featuring BBK's patented adjustable power valve, the systems come complete with two tunable VariTune performance mufflers engineered with the high-flow direct fit stainless steel tubing and hardware for an easy bolt-on installation. They include a pair of stylish 4 in. stainless tips to deliver good looks along with maximum performance. The performance mufflers that can be adjusted for sound and horsepower, from underneath the car, by simply moving the adjustment screw in or out. VariTune mufflers utilize a unique internal power valve that when in the closed position blocks the exhaust flow, forcing it through all three chambers of the muffler for a classic mellow sound. When in the open position, the valve opens the exhaust flow allowing it to take the path of least resistance, acting more like a straight-through muffler for an aggressive throaty exhaust note. Simple, yet effective, the BBK VariTune rear axle back exhaust systems deliver the most performance, while allowing you to tune to the desirable level.
