Transform the sound and performance of your BMW with the Remus Axle Back Exhaust System for the F20/F21 M135i and F22/F23 M235i (N55 engine). Designed to fit both pre-LCI and LCI models, this premium system combines Austrian craftsmanship with motorsport-inspired engineering to deliver a sharper exhaust note, improved performance, and a perfect OEM+ fit. Remus offers flexibility to suit your preference: choose between a standard rear silencer for a refined upgrade or a racing rear silencer for an aggressive, track-ready tone. For those seeking maximum performance and sound, a resonated cat-back mid-pipe is also available as an optional add-on. This system can be configured with black chrome exhaust tips featuring carbon fibre inserts or supplied without tips if you prefer a different finish. Every unit is constructed from 100% stainless steel, shot blasted for durability, and engineered for low back pressure, ensuring both sound and performance gains. For maximum sound & performance gains, we recommend adding the Remus cat-back front section.
