Product Details

Worn-out exhaust causes poor sound and performance. This BBK VariTune axle back exhaust kit is a direct fix for your 2005-2010 Mustang GT. It features patented adjustable power valves inside the mufflers, letting you control exhaust flow for a custom sound and added performance. The kit includes everything needed for a bolt-on installation.

The mufflers are made from 439 stainless steel for durability. You can adjust the sound level between 8-10 decibels and potentially gain 10-15 horsepower by moving the valve in or out with a wrench.
