This mid-pipe runs from the downpipes to the stock rear silencer, deleting the center silencer, secondary cats and OPF. It converts the exhaust track from a double pipe into one. This results in a more full-bodied exhaust sound with a deep tone. 
Requires an ECU tune (recommended) or OPF deleter unit which removes the OPF fault codes (since it's gone). Available for G8x M2/M3/M4

Comes with all necessary OEM clamps.
