Description
Boost performance and sound on your Porsche 958 Cayenne Turbo / Turbo S V8 4.8L with the CARGRAPHIC Secondary Sport Catalytic Converter Set.
This system replaces the factory secondary catalytic converters with high-performance 100 CPSI HJS Motorsport catalytic converters for maximum exhaust flow and enhanced acoustics. Built from SS304L lightweight stainless steel and engineered with CNC mandrel-bent pipework, this upgrade reduces backpressure, sharpens throttle response, and delivers a deeper, more aggressive exhaust tone — all without triggering a Check-Engine Light (CEL) or requiring ECU/DME reprogramming.
Designed for motorsport use only (SUPER SOUND export version), this setup ensures no drone or resonation, even when paired with additional CARGRAPHIC exhaust components.
