Scorpion Secondary Catless Pipe - BMW M3 (F80) / M4 (F82/F83) - 70mm
For race use only. This is a catless part for off-road and competition vehicles. It has no catalytic converter and is not legal on a road-registered vehicle in Australia.
This Scorpion section replaces the secondary catalysts on the BMW M3 (F80) and M4 (F82/F83) with 70mm (2.75") T304 stainless pipework. It suits both GPF and non-GPF cars and works with the factory exhaust or a Scorpion system.
Note: The factory system must be cut to fit unless Scorpion's SBMS073 or SBMS073C system is fitted. Australian-delivered M3 and M4 have no GPF. An engine management light may come on, and Scorpion recommends a Stage 2 ECU remap. Installation by a professional is recommended.
Features
- 70mm (2.75") T304 stainless pipework
- Replaces the secondary catalysts
- Suits GPF and non-GPF cars
- Weighs 7.3kg
