Restore the rear exhaust system of your Porsche 911 (996-series) with these genuine OEM mufflers. Designed for 2002-05 Porsche 911 Carrera/Carrera 4 models, these silencers deliver direct-fit replacement, correct hanger mounting, factory tail-pipe alignment and authentic acoustic performance.
Fits:
- Porsche 996 C2 3.6L 2002-2005
- Porsche 996 C4 3.6L 2002-2005
- Porsche 996 C4S 3.6L 2002-2005
What This Product Does:
- The muffler (silencer/back-box) is the final large component in the exhaust system: it reduces noise, completes the exhaust flow path, and ensures the exhaust gases are safely expelled under the rear of the vehicle.
- It helps maintain the correct back-pressure, supports the exhaust hangers and alignment, and plays a role in sound tuning (ensuring the vehicle meets factory acoustic specification).
- Correct fitment ensures the tailpipes, hangers, connections and appearance align with factory standards—especially important for OEM look, sound, and performance.
- Excessive noise, harsh exhaust tone, or sudden change in sound (potential sign of internal baffle damage or leaks).
- Visible corrosion, holes, cracks or rust on the muffler body or tail-pipe connections—common on older 996 cars.
- Poor fitment or misalignment of the muffler/tailpipe assembly (exhaust shifting, visible sagging or melted brackets).
- Reduced performance / overheating of nearby components due to exhaust misalignment or exhaust gases contacting bodywork.
- Bad or broken mounting/hanger points causing vibration or movement under load.
Why Replacement Matters:
- Replacing worn or damaged mufflers restores correct sound, fit and backing support of the full exhaust system.
- Maintains factory appearance and acoustic characteristics — important for value, authenticity and drive-quality in the 996 series.
- Prevents further damage: a failing muffler may lead to hanger failure, alignment issues or heat damage to nearby components.
- Enhances reliability: a fresh muffler assembly means fewer leaks, less corrosion risk and better longevity of the rear exhaust section.
