Transform the sound and performance of your Porsche 997.2 with the CARGRAPHIC Sport Rear Silencer Set featuring integrated PLO (Pressureless Open) exhaust valves. Engineered and manufactured in Germany, this premium performance exhaust system delivers enhanced acoustics, improved throttle response, reduced backpressure, and increased power while maintaining exceptional everyday drivability with no unwanted drone or resonance.
Designed for drivers seeking a sharper, more aggressive Porsche exhaust tone, the CARGRAPHIC Sport Rear Silencer Set produces a deeper low-frequency sound at cruising speeds while delivering a crisp, volume-enhancing motorsport character under acceleration and higher revs.
The absorptive silencer design combines CNC mandrel-bent pipework with lightweight SS304L stainless steel construction for maximum flow efficiency, durability, and reduced system weight. The specially produced concave domed end baffles optimise both sound quality and structural stability.
This system is compatible with original Porsche tailpipes or CARGRAPHIC sport tailpipes. Vehicles fitted with factory Porsche Sport Exhaust (PSE) tailpipes require the optional adapter set (Part No. CARP97DFIPSELP).
Dyno-tested performance improvements of up to 7kW (10PS) and 10Nm of additional torque help improve throttle response, freer revving characteristics, and overall engine performance.
