These all new high performance premium mufflers let 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 the BBK Varitune has 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.
These mufflers are now available from Brothers Performance in aluminized or stainless steel, in 2.5", 2.75" and 3.0" and with an offset/offset design that fits many aftermarket and OEM applications.
