This Scorpion F22 M235i Cat-Back System runs from the downpipes-back to remove the secondary cats. This significantly optimises exhaust flow and is a great way to add to the visual and aural experience.


This system has an in-built valve as with the standard system. The OEM controller can be carried over for a seamless fit. This system will also fit with both the standard and the M Performance valance thanks to adjustable tailpipes.


For a full turbo-back system combine with a Scorpion M235i Sport Cator De-Cat Downpipe. This system bolts directly to the OEM system and uses factory mounting locations. Optional black ceramic tailpipe finish gives a great stealthy look to the system.
