Active Autowerke's downpipe for the 2016+ BMW M240i, 340i, and 440i (B58 engine) improves exhaust flow for enhanced turbo response by replacing the restrictive OEM downpipe.

This downpipe optimizes turbocharger spool by enabling faster exhaust gas evacuation while maintaining emissions compliance under federal EPA standards (except California). It supports forced induction setups without sacrificing engine performance or triggering emissions warnings.

Note: Not legal for use in California per state vehicle code sections 27156 and 38391. Federal law prohibits tampering with emissions control devices; this part meets EPA standards for aftermarket repair or replacement.
