This kit is designed to permit instant manual bypass of the two exhaust valve butterfly valves present in the Corvette muffler, giving the driver full control of maximum exhaust flow. The 182-102157 is a Plug-And-Play design which should take the average person around 20 minutes to install. (NOTE: Kit is also available WITHOUT switch plate, Part Number 182-102158 is intended for those who want to mount the switch in an alternate spot). There are no wires to cut, and no electrical skills are necessary to install this system, which comes with the console cover plate to replace your OEM part. The switch used has a small logo identifying four exhaust ports. When the switch is pressed to the position of the white dot, the exhaust butterfly valves open and remain on manual override until the switch is returned to the normal position.
