How do I adjust the sound and performance of the Varitune mufflers?

You can adjust the Varitune mufflers using a wrench on the rear of the muffler. Moving the internal power valve in or out changes the exhaust flow, allowing you to personalize the sound and power levels. Once you're happy with the setting, a locking nut secures the valve in place.

What material are the exhaust tips made of?

The exhaust tips included with this kit are made of brushed stainless steel, measuring 3.5 inches in diameter. Stainless steel is chosen for its resistance to corrosion and its clean appearance.

Does this kit include all the necessary hardware for installation?

Yes, this cat-back exhaust system is designed as a direct bolt-on replacement and includes the necessary hardware, hangers, and clamps for installation.

Product Details

BBK has been making performance parts for decades, and this Varitune cat-back exhaust system for your 1986-2004 Ford Mustang is one of their staples. This kit replaces your restrictive factory exhaust with a system designed to improve both sound and performance. The heart of this system is BBK's patented Varitune mufflers, which feature an internal power valve that you can adjust with a wrench. By moving this valve in or out at the rear of the muffler, you can fine-tune the exhaust flow through the muffler's chambers. Once you find the sound and performance level you like, a locking nut keeps the valve in place.

The Varitune power valves are constructed from stainless steel for lasting durability and smooth operation. BBK claims this adjustability can change your car's sound level by 8-10 decibels and add 10-15 horsepower. The rest of the system is built with aluminized steel, which offers good corrosion resistance, and it's topped off with 3.5-inch brushed stainless steel tips for a clean look. This kit is designed as a direct bolt-on replacement, meaning it should fit right in place of your factory exhaust without needing any welding or cutting.

This specific kit is designed for most 1986-2004 Ford Mustangs. However, it does not fit the 1986-1993 Mustang GT models that have factory turn-down exhaust tips; for those, you'll need part number 3002. The kit includes the two Varitune mufflers, necessary hardware, hangers, clamps, and the stainless steel tips.
