The OE-style internal design ensures optimum exhaust gas flow, effective noise reduction and correct back pressure for reliable engine performance. Precision-manufactured for direct OE-style installation, it offers a straightforward replacement for worn or damaged original rear silencers.
What This Product Does:
- Channels exhaust gases safely from the engine.
- Reduces exhaust noise through an OE-style silencer design.
- Maintains correct exhaust back pressure for efficient engine operation.
- Supports smooth and unrestricted exhaust gas flow.
- Features a 2-inlet, 1-outlet configuration with a Ø70mm tailpipe.
- Restores the factory appearance and exhaust note.
- Helps optimise engine performance and drivability.
- Forms an essential part of the vehicle's exhaust system.
Symptoms Of Wear Or Failure:
- Excessively loud exhaust noise.
- Blowing or leaking exhaust gases.
- Visible rust or corrosion on the silencer.
- Holes or cracks in the exhaust casing.
- Rattling caused by loose internal baffles.
- Reduced engine performance due to exhaust restriction.
- Exhaust fumes entering beneath the vehicle.
- Loose or damaged exhaust mounting points.
- Increased vibration from the exhaust system.
- MOT or vehicle inspection failure due to exhaust leaks or excessive emissions.
Why Replacement Matters:
- The rear exhaust silencer operates under extreme temperatures and is continually exposed to moisture, road salt, vibration and condensation. Over time, internal corrosion, external rust and metal fatigue can weaken the silencer, reducing its ability to control exhaust flow and noise effectively.
- A damaged rear exhaust can cause exhaust leaks, increased noise levels, reduced engine efficiency and unwanted vibration. In severe cases, leaking exhaust gases may pose a safety risk while placing additional strain on other exhaust system components.
- Replacing a worn or damaged rear exhaust restores correct exhaust flow, factory sound levels and reliable engine performance. The OE Match replacement provides factory-style fitment, durable construction and long-lasting corrosion resistance, ensuring dependable performance, improved refinement and the authentic driving experience expected from your Porsche.
