Installation and Usage

A specialist exhaust or BMW performance workshop should install this downpipe. The factory downpipe and catalytic converter must be removed, oxygen sensors transferred and the new pipe aligned with the turbo and mid-pipe. Engine management calibration will likely be needed to avoid fault codes. After fitting, inspect joints for leaks and confirm clearances from heat-sensitive parts.

Important Fitment Notice

This catless downpipe is intended for motorsport and off-road use only. In New Zealand, removing a catalytic converter from a road vehicle can breach emissions rules and cause a Warrant of Fitness failure, and exhaust noise limits still apply. Please send us your VIN before ordering so we can help confirm fitment. Because several BMW chassis are listed for a single part, confirming your exact model, build date and any existing exhaust or tuning modifications is especially important for this downpipe.
