Utilizes turndown tips to clear the factory rear bumper cover.
These American designed and built performance mufflers are the first of their kind in the aftermarket fully adjustable performance mufflers that can be adjusted for sound and horsepower by simply moving the adjustment screw in or out from underneath the car! 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 mellow 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.
BBK Varitune exhaust kits are engineered and built with large 2-3/4" CNC mandrel bent aluminized tubing for unrestricted exhaust flow. These kits are direct fit and include all hardware required for a true bolt on installation.
