All BBK axle back exhaust systems feature BBK Varitune mufflers that have a patented adjustable power valve inside to allow for full adjustment of the exhaust flow through the muffler chambers. This gives your Mustang a great sound and added performance. This adjustment is made at the rear of the muffler with a wrench by moving the valve in or out.
All of the Varitune power valves are made with stainless steel for lasting durability and smooth operation. All kits are a direct bolt on replacement for the factory exhaust. Each kit includes BBK stainless steel tips.
? Designed and built with 304 stainless for years of maintenance free performance
? Adjustment of the sound and HP levels to suit your performance needs
? Dyno testing has shown a consistent 10-15 HP increase at the rear wheels over stock.
