Remus axle‑back exhaust for 2011 BMW 1 Series F20/F21 replaces the rear section and includes 84mm carbon ring tail pipes plus a front silencer to refine sound. Built for the F20/F21 platform, the kit concentrates installation at the rear while the front silencer helps keep interior resonance in check. The result is a neater rear appearance with a controlled exhaust voice.
