Installation and Usage

A specialist exhaust or BMW performance workshop should carry out installation. Access to the downpipes requires removing underbody panels and exhaust sections, and oxygen sensors must be transferred carefully. Engine management calibration is likely to be required to avoid fault codes. After installation, check every joint for leaks, confirm clearance from heat-sensitive parts and recheck fasteners once the system has heat cycled.

Important Fitment Notice

This part is intended for motorsport and off-road use. In New Zealand, removing or altering factory emissions equipment on a road vehicle can breach emissions rules and lead to a Warrant of Fitness failure, and exhaust noise limits still apply. Please send us your VIN before ordering so we can help confirm fitment, and speak with a certifier if your car is road registered.
