Breaking the boundary between originality has become a habit with DUKE DYNAMICS and our innovative products. As we look closer at the new E90 M-Tech quad diffuser we notice that the research and development invested into the manufacturing of this product was more than just intensive.

We extended the fins inward by 2.5cm; to enhance the looks of the performance quad diffuser and add extra aerodynamics to the designs.

- Fits both E90 and E91 M-Technik rear bumper

- Eisenmann Race/Sport Quad Exhaust

- Autobahn Exotics (AE) Exhaust System

- Meisterschaft

- Remus Quad Exhaust

- Fit Custom made quad tips or exhausts.

Note: If you have an older of the M-Tech ('06-'08 pre-LCI model) rear bumper, you'll to need to modify (trim) the corners of the bumper in-order to fits probably.
