Black Series Sport Cat Downpipes
Sport cat downpipes for the Mercedes-AMG GT Black Series, replacing the restrictive factory 800-cell catalytic converters with HJS Germany tri-metallic 200-cell cats designed specifically for this model. Laser-scanned and CAD-designed for a perfect factory fit, they're built from 14-16 gauge mandrel-bent T304L stainless steel and wrapped in 2000°F-rated heat protection. Fabspeed rates the same catalyst design to support over 1500whp, and guarantees no catalyst-triggered check engine light on US cars. Simple bolt-on installation, no cutting or welding required.
