Scorpion BMW F80 M3 & F82/F83 M4 High Flow Secondary Sports Cat Section

Enhance performance and unlock a richer, more aggressive exhaust tone with the Scorpion High Flow Secondary Sports Cat Section, designed specifically for the BMW F80 M3 and F82/F83 M4. This premium upgrade replaces the factory secondary catalytic converters with high-flow 200-cell sports cats, allowing for significantly reduced exhaust back pressure while maintaining road-legal emissions control.

Manufactured in the UK from T304 stainless steel, the precision-engineered 70mm (2.75") diameter pipework ensures optimal flow and durability. The direct-fit design maintains compatibility with the OEM and most aftermarket exhaust systems, making it an ideal upgrade for owners looking to improve throttle response, increase tuning potential, and enhance overall sound character—all without going fully decat.

Whether as part of a staged tuning upgrade or a standalone enhancement, Scorpion’s sports cats offer an ideal balance of performance and compliance.
