Remus BMW M3/M4 GPF Back Exhaust System is a state-of-the-art exhaust system for the G8X platform. This is exactly the same system as the racing rear silencer axle-back system with the addition of a front silencer replacement tube between the axle-back and the vehicle's GPF.
The addition of this midpipe offers a further reduction in back pressure, slightly higher tuning potential and a greater-enhanced exhaust note.
The Racing Rear Silencer offers:
- 6mm larger tube diameter
- Two smaller silencers in the place of the single factory backbox 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.
