    These American designed and built performance mufflers are the first of their kind in the aftermarket fully adjustable performance Mufflers that can be adjusted for sound and horsepower 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 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.

    Quality Materials
    Manufactured using the highest quality heavy gauge aluminized steel available, BBK Performance utilizes both robotic and hand welding to ensure the quality and durability of each of their mufflers.

    Great Sound - Love these Mufflers Couldnt wait to get these installed on my Fox body - pretty much a straight swap - just needed to use a good amount of WD40 to help get the old ones out and a small butane torch to help get my old flowmasters out - after i adjusted them a bit - i have a great sounding mustang with extra horsepower I would definitely recommend this.
