Remus BMW M3/M4 Racing Downpipe Back Exhaust System is a state-of-the-art exhaust system for the G8X platform. This is exactly the same system as the racing GPF-back system with the addition of a GPF replacement tube, as well as a secondary cat replacement tube.
The addition of these upgrades offers the highest reduction in back pressure, much 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.
DISCLAIMER
This item is not intended for use on the public road (track use ONLY) as it does not comply with UK emission standards.
