Exhaust Control Valve 3,5" ( 89mm ) , Electric Exhaust Butterfly aluminum pair

With Quick Time electric cutouts, you can have the best of both worlds--they're quiet for the street and wide-open for the strip. These electrically controlled exhaust valves bolt to standard cutouts and can be opened and closed from inside of the car with the flip of a switch. Using the convenient interior-mounted switch, you can go from stealth-quiet to wide-open power. You control the volume and the flow. Quick Time exhaust cutouts fit any car or truck, from old-school musclecars to high-tech imports.
