Scorpion Exhausts Back-Box for E46 M3.

As the official technical partner to the Airwaves BMW BTCC team, Scorpion knows exactly how to extract the best performance from high performance BMW engines.

This Scorpion E46 M3 Rear Silencer or Back-box optimises exhaust flow and is a great way to add to the visual and aural experience. Does not affect emissions or MOT-compliance.

This backbox bolts directly to the OEM system and uses factory mounting locations. Combine with Hack Engineering Billet Exhaust Hangers for an optimal maintenance-free fit. For a fuller system with greater gains, see the Scorpion Cat-Back System.
