Remus BMW M3/M4 Axle Back Exhaust System (G80/G81/G82/G83)

Remus BMW M3/M4 Axle-Back Exhaust System is a state-of-the-art exhaust system for the G8X platform, offering more efficient airflow to unlock increased tuning potential. It also creates a fantastic exhaust note.

There are two axle-back rear silencers to choose from:

Remus Rear Silencer

- 6mm larger tube diameter
- Absorption principal
- One large singular silencer

- EC type approval - This means the system has been homologated & is legal for road use.

Racing Rear Silencer

- 6mm larger tube diameter
- Two smaller silencers for better airflow
- No EC type approval - This means the racing system is, generally, not legal for road use in Europe. Should be used for motorsport/track ONLY.

Both systems on constructed using 100% high-grade stainless steel with a shot-blasted surface. Back pressure is dramatically reduced, offering quicker throttle response and greater tuning potential. They both come with a range of exhaust tip options & use the OE valve control system for seamless integration.

Remus have been manufacturing high-quality exhaust systems for over two decades, even producing OE components and systems for well-known vehicle manufacturers. When you purchase Remus products, you can have full confidence you are getting outstanding quality, fitment & durability.
