BBK Varitune performance mufflers utilize a unique internal Power Valve. When in the closed position the valve blocks the exhaust flow, forcing it through all three chambers of the muffler for a classic deep sound. When in the open position, the valve opens the exhaust flow allowing it to take the path of least resistance, acting more like a straight-through muffler for an aggressive, throaty exhaust note.
