The BBK Varitune performance mufflers utilize an internal "Adjustable Power Valve" that can be adjusted by you any time you want with a wrench from under the car . When in the closed position the valve blocks the exhaust flow forcing it through all three chambers of the muffler for a great classic mellow sound. When in the full open position the valve opens up the exhaust flow allowing it to flow like a straight through muffler for a rich throaty wide open exhaust note.
