Description
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. Our Sport Cat Downpipe flows 93% of a 3'' straight pipe, delivering emissions-compliant performance without triggering a check engine light. No need for cat bypass pipes!
Sound:
The Sport Cat Downpipe subtly increases exhaust volume and enhances deceleration pops and burbles without adding unwanted interior drone. For a more aggressive exhaust note, pair it with our Intermediate X-Pipe.
Power:
On our in-house DynoJet, the high-flow Sport Cat 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. Power gains are evident throughout the entire power band.
