Unlock more from your B58-powered BMW with this 5-Inch Heat-Shielded Catless V-Band Downpipe, intended for compatible G42 M240i and G20 M340i OPF models. Designed to replace the restrictive factory downpipe, its free-flowing construction helps reduce exhaust backpressure and supports increased performance when paired with suitable tuning.
The heat-shielded body helps limit radiant heat reaching surrounding components, whilst the catless design brings out a louder, more aggressive exhaust note. The final sound will depend on your remaining exhaust system, including whether the factory OPF is retained. Featuring a V-band connection for the matching OPF exhaust configuration, this version is designed for vehicles with the corresponding connection.
For off-road and motorsport use only. Professional installation recommended.
