Description
Enhance the performance and sound of your BMW M3 or M4 with the Scorpion Exhaust Secondary High-Flow Sports Catalyst Section, precision-engineered for the F80 M3 and F82, F83, F84 M4 platforms. Designed to replace the restrictive OEM secondary catalytic converters, this high-performance upgrade significantly improves exhaust gas flow, unlocks horsepower, and delivers a more aggressive exhaust note.
Constructed from premium T304 aircraft-grade stainless steel with a 70mm (2.75-inch) diameter, this high-flow catalyst section offers superior durability, corrosion resistance, and a noticeable reduction in backpressure. Its free-flowing design allows your twin-turbo 3.0L engine to breathe more efficiently, resulting in sharper throttle response and increased mid-to-top-end power.
This system is a direct fit to either the OEM or Scorpion exhaust system. Please note, installation on OEM systems requires cutting unless used in conjunction with Scorpion’s SBMS073 or SBMS073C front sections. Due to the increased exhaust flow, an engine management light (EML) may activate; a Stage 2 ECU remap is recommended to optimize performance and maintain drivability.
Perfect for enthusiasts seeking a more dynamic driving experience, Scorpion’s hand-crafted exhaust components are renowned for their race-inspired engineering, Red Power acoustics, and unmatched UK craftsmanship.
