BMW 135i Performance Exhaust - Rear - Dinan - Axle Back, Freeflow - Black - '08-'13. This Dinan system brings a deeper, sportier tone and freer flow to your E82/E88 135i or 135is.

Engineered to cut backpressure and weight while preserving daily comfort, the Free Flow axle-back is built from 100% 304 stainless and mounts to the factory brackets and hangers. Drone abatement reduces cabin resonance, and dual 3.5" ceramic black, laser-engraved tips deliver a purposeful finish. Dinan reports gains of up to +6 hp and +5 lb-ft at 6600 rpm with a refined soundtrack that stays civil on cruise and assertive under throttle.
