BBK Performance 2-3/4” Vari-Tune Performance Muffler, Aluminized

When our engineers started out developing a clean sheet design line of performance mufflers and cat back/axle back systems for the popular Mustang, Camaro and Challenger/Charger models they brought to the table over twenty years of American engineering experience to come up with something completely evolutionary. The final product is an all new high performance premium muffler that actually let’s you easily adjust both the sound and performance levels while doing so at a price competitive with other standard performance mufflers. Utilizing a patent pending adjustable chamber valve assembly these new mufflers have undergone hundreds of hours of testing which revealed such results as the ability to modify sound levels up to 8 decibels across the adjustment range while adjusting power levels at the same time. Now enthusiasts can set the system to the desired sound and performance levels then a adjust at any time in about 5-minutes on the car for better track or street performance or for a mellow sound for a long road trip. These new mufflers are sold individually and are available in an aluminized or stainless case and in 2-1/2”, 2-3/4” or 3” double offset versions.
