This replacement, direct-fit exhaust gasket is manufactured to OEM dimensions standards for a perfect, leak-free seal and long-lasting performance.
Fits:
Porsche 993 1994 - 1998
* Gillet Heat exchanger to pre-silencer (diagram ref no 6) or heat exchanger to cross over pipe (diagram ref no 10)
Porsche 928 1978 - 1992
* Manifold to down pipes (diagram ref no 11) or down pipes to rear silencer (diagram ref no 11)
This gasket provides a gas-tight seal between exhaust components—typically between the exhaust manifold, catalytic converter, or connecting pipes—to prevent exhaust leaks, maintain backpressure, and ensure proper sensor readings. Its heat-resistant composite construction withstands extreme temperatures, vibration, and exhaust gas exposure.
• Used in the exhaust system joints of various Porsche models,
• Commonly fitted between exhaust flanges or at the manifold-to-pipe or pipe-to-catalytic converter junctions
• Direct-fit installation with OEM-style flange geometry—no modifications required
Over time, original gaskets can compress, burn through, or crack from heat cycling and vibration, causing exhaust leaks, noise, or loss of performance. Replacing it with a high-quality OE Match gasket restores proper sealing, maintains exhaust efficiency, and prevents damaging heat or gas leaks near sensitive components.

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
