This kit is designed to permit instant manual bypass of the two exhaust valve butterfly valves present in the Z06 and Grand Sport muffler, giving the driver full control of maximum exhaust flow. The 102158 is a Plug-And-Play which includes only the switch and plug-in harness. There are no wires to cut, and no electrical skills are necessary to install this system. 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. |
