Sport Cat Downpipe

Give your G8x M2/M3/M4 more sound and power with Fabspeed's high-flow catted downpipe, engineered in collaboration with HJS Motorsport. This downpipe features the largest HJS catalytic converter that fits the G8x chassis, ensuring optimal exhaust flow, reliability, and sound. The Sport Cat Downpipe flows 93% of a 3'' straight pipe, delivering emissions-compliant performance without triggering a check engine light. It subtly increases exhaust volume and enhances deceleration pops and burbles without adding unwanted interior drone. On Fabspeed's in-house DynoJet, the downpipe achieved max gains of 23 ft/lbs of torque at 3,200 RPM and 20 WHP at 6,500 RPM, equating to 23 crank HP, with gains evident throughout the entire power band. Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel, it offers durability and performance. Installation is a simple bolt-on process requiring no cutting or welding. The downpipe saves 2 lbs compared to the factory system and is backed by the Fabspeed Lifetime Warranty. It fits all BMW M2, M3 & M4 (G80/G82/G87) sedan/coupe vehicles, including Competition Models worldwide from 2021+ (RWD & AWD).
