- Prevents exhaust gas leaks at the exhaust port
- Maintains proper exhaust flow and system efficiency
- Supports engine performance and combustion efficiency
- Reduces exhaust noise caused by leaking exhaust joints
- Withstands high temperatures and exhaust system pressures
Symptoms Of Wear Or Failure:
- Creates a gas-tight seal between the heat exchanger and cylinder head
- Prevents exhaust gas leaks at the exhaust port
- Maintains proper exhaust flow and system efficiency
- Supports engine performance and combustion efficiency
- Reduces exhaust noise caused by leaking exhaust joints
- Withstands high temperatures and exhaust system pressures
Why Replacement Matters:
- Restores a reliable gas-tight seal at the cylinder head
- Prevents exhaust leaks and associated noise

Information
Exhaust gasket rear silencer
This gasket is used to seal the joint between the rear silencer (muffler) and the heat exchanger flange on classic Porsche 911 and 914/6 models, ensuring a tight, leak-free connection in the exhaust system.
Sold each, Typically two gaskets are required when reinstalling the exhaust rear silencer.
Fits:
Porsche 911 1965 - 1973 (need 2 pcs)
Porsche 914/6 1970 - 1972 (need 2pcs)
Diagram ref no 8
• Application: Seals the connection between the rear silencer (muffler) and the adjacent exhaust pipe/heat exchanger flange on classic air-cooled Porsche engines.
Installed at the rear silencer interface of the exhaust system, this gasket ensures:
• A secure, leak-resistant seal between exhaust components
• Smooth exhaust gas passage without loss of power or noise
• Reduced risk of harmful fumes entering cabin areas.
It is made to withstand the high heat and vibration levels typical of classic Porsche exhaust systems, and matches the original Porsche design for long-lasting performance.
Over time, the original exhaust gaskets can crack, harden, or deteriorate due to heat cycles, vibration, and corrosion. A worn or ineffective gasket can lead to:
• Exhaust leaks at the silencer joint
• Increased exhaust noise
• Reduced engine efficiency and performance
• Fumes entering the undercarriage or cabin
Replacing exhaust gasket restores proper sealing, preserves exhaust flow integrity, reduces noise, and helps maintain emissions compliance on classic Porsche vehicles.
Replace the exhaust rear silencer gasket if you notice:
• Audible exhaust leaks near the silencer connection
• Increased cabin noise or exhaust rasp
• Visible gasket deterioration or rust
• During exhaust system removal or reinstallation
