CARGRAPHIC Sport Rear Silencer Set with Integrated Exhaust Valves 

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.

Fits:

• Porsche 997 MKII Carrera C2 3.6L 2009-12
• Porsche 997 MKII Carrera C4 3.6L 2009-12
• Porsche 997 MKII Carrera C2S 3.8L 2009-12
• Porsche 997 MKII Carrera C4S 3.8L 2009-12

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.

For Porsche owners seeking the enhanced sound, performance and quality of the CARGRAPHIC valved exhaust system while retaining the factory appearance of the original Porsche Sport Exhaust tailpipes, these adapters provide the perfect solution.

Precision engineered for a direct and secure fit, the adapters bridge the dimensional differences between the CARGRAPHIC rear silencer outlets and the factory Porsche PSE tailpipe assemblies. This ensures correct alignment, secure mounting and a professional OEM-quality finish.

What Does the CARGRAPHIC Tailpipe Adapter Do?

The tailpipe adapter allows OEM Porsche Sport Exhaust tailpipes to be fitted to the CARGRAPHIC valved rear silencer system.
