BBK Aluminized Varitune Offset/Offset Oval Muffler; 3-Inch (Universal Fitment)
Adjustable Sound. BBK's patented tunable Varitune performance mufflers allow you to change from a mellow three chamber exhaust sound to a rich throaty straight-through exhaust note with just a twist of a wrench, for a 8 to 10 decibel sound level difference!

How It Works. BBK Varitune performance mufflers utilize an internal "Adjustable 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 "uncorks" the exhaust flow, allowing it to take the path of least resistance, acting more like a straight-through muffler for a rich throaty exhaust note. This unique design is perfect for personalizing the power and sound levels of your Mustang to suit your own specific needs.

Aluminized Steel Construction. 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.

Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.

Application. This BBK Varitune Muffler features a 3" inlet and outlet diameter in an offset configuration making it the perfect muffler for 1979 to 2004 Mustangs, including the LX, V6, GT, Bullitt, Mach 1 and 1994-1998 SVT Cobra models. Excludes 1999-2004 SVT Cobras with IRS.
