This Scorpion F20/F21 M135i 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.

 

For a full turbo-back system combine with a Scorpion M135i 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.
