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)

• 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

OEMatch Exhaust Gaskets — Flow, Response, Refinement
Exhaust gaskets form essential seals within Porsche exhaust systems. OEMatch supplies a selection of exhaust gaskets for Porsche models to restore sealing between manifolds, headers, pipes and catalytic converters. Choosing the correct profile and material helps prevent leaks, reduce noise and protect nearby components from heat damage.
Available Types
- Manifold-to-downpipe flange gaskets
- Header and collector gaskets
- Catalytic converter and connector gaskets
- Ring and multi-layer steel (MLS) exhaust seals
Understanding OEMatch Exhaust Gaskets
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original exhaust gaskets.
OE (Original Equipment) refers to parts matching original specifications for the exhaust gaskets and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM exhaust gaskets engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Exhaust gaskets create airtight seals at joints and flanges to control gas flow and maintain correct back pressure. Materials range from composite fibres and graphite to metal-reinforced and multi-layer steel constructions chosen for temperature resistance and corrosion durability. Correct sealing supports sensor operation, emissions control and engine efficiency while limiting exhaust noise and vibration.
Benefits Include
- Tight sealing to prevent exhaust leaks and maintain back pressure
- Reduced exhaust noise and vibration
- Protection of nearby components from heat and corrosive gases
Why Exhaust Gaskets Wear and Fail
- Repeated thermal expansion and contraction leading to cracking or deformation
- Corrosion from moisture and road salt attacking metal layers
- Vibration and joint movement causing material fatigue or loss of compression
- Incorrect installation or uneven flange contact causing leaks
The Importance of Replacing with OEMatch Exhaust Gaskets
Replacing worn or damaged gaskets restores proper exhaust sealing for Porsche models and helps retain engine performance, emissions control and component life. Many owners search for genuine or OEM exhaust gaskets; these are direct-fit alternatives designed to match the original form, fit and function. Selecting the correct gasket type for the exhaust joint reduces the risk of recurring leaks and downstream damage to manifolds, sensors and catalytic converters.
Advantages
- A choice of materials and profiles matched to common Porsche flange types
- Options suited to restoration, routine maintenance or higher-temperature applications
- Clear identification by application to help confirm fit for model and engine
