Scopion Turbo Downpipe - BMW F20 M140i Non-GPF Model

BMW F20 M140i Non-GPF Model - Turbo Downpipe

Unlock improved exhaust flow, sharper throttle response and enhanced tuning potential on your BMW M140i F20 or F21 GPF model with the Scorpion 5" Downpipe with High Flow Sports Catalyst. This performance downpipe is engineered with a large-bore 5-inch design and an integrated 200-cell high flow sports catalyst, delivering substantially greater gas flow compared to restrictive factory components.

Manufactured from T304 stainless steel with CNC mandrel-bent construction, this downpipe reduces back-pressure, helping the turbo work more efficiently and supporting potential increases in power when combined with tuning and supporting modifications. The integrated sports catalyst also offers improved flow versus the standard particulate filter section, while maintaining a catalytic function — a compromise between unrestricted flow and controlled emissions.

This performance downpipe is ideal for enthusiasts looking to extract more from their M140i, particularly when used as part of a staged performance build. The robust construction and precision engineering ensure reliable fitment and durability under demanding conditions.

⚠️ Important – Motorsport Use Only:
This component alters factory emissions control equipment and does not meet road-legal emissions standards in the UK and EU. It is intended for off-road or motorsport use only and may cause warning lights or MOT/emissions test failures.
