PitStopUSA.com - BBK Performance Varitune Mufflers

BBK Varitune mufflers are American designed and built and are the first of their kind in the aftermarket fully adjustable performance Mufflers. They can be adjusted for sound and exhaust flow by simply moving the adjustment screw in or out from underneath the car. BBK Varitune performance mufflers utilize a unique internal Power Valve. When in the closed position the valve blocks the exhaust flow, forcing it through all three chambers of the muffler for a classic deep 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. BBK 3" Varitune mufflers are manufactured using the highest quality heavy gauge stainless steel available. Stainless mufflers feature a 439 stainless teel case and 304 stainless steel tubing. BBK Performance utilizes both robotic and hand welding to ensure the quality and durability of each of their mufflers.
