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.

Exhaust Gaskets for Porsche | Precision Seal & Performance Reliability
Exhaust gaskets are crucial components in your Porsche’s exhaust system, ensuring a tight, leak-free seal between joints and flanges. They prevent exhaust gases from escaping, maintain correct back pressure, and protect nearby components from heat and harmful emissions.
At Design911, we supply a full range of exhaust gaskets designed for Porsche vehicles — from classic air-cooled 911s to high-performance modern models. Manufactured from high-temperature, corrosion-resistant materials, these gaskets deliver durability and a perfect seal under extreme conditions.
Whether you’re installing a new exhaust, replacing worn components, or upgrading for performance gains, our high-quality Porsche exhaust gaskets guarantee a reliable fit and long-lasting performance.
What Do Exhaust Gaskets Do?
Exhaust gaskets form airtight seals between the various components of the exhaust system, such as manifolds, headers, pipes, and catalytic converters. They play a vital role in maintaining system integrity, performance, and emissions control.
Core Functions:
- Seals
exhaust joints to prevent leaks and gas escape.
- Maintains
back pressure for efficient engine performance.
- Reduces exhaust noise and vibration.
- Protects against heat and gas damage.
- Ensures compliance with emissions standards.
A properly fitted gasket ensures that exhaust gases are channelled efficiently through the system — essential for power, fuel economy, and emissions control.
Why Do Exhaust Gaskets Fail?
Over time, exhaust gaskets are subjected to extreme heat, pressure, and vibration, which can lead to wear or failure.
Common Causes of Failure Include:
- Thermal
expansion and contraction causing cracks or deformation.
- Corrosion
from moisture or road salt exposure.
- Improper installation or over-tightening.
- Aging
and fatigue of gasket material.
- Exhaust vibration leading to joint loosening.
When a gasket fails, you may notice hissing or tapping noises, a burning smell, or loss of engine performance. Exhaust leaks can also increase harmful emissions and damage surrounding components.
Why Replace Your Exhaust Gaskets?
Replacing worn or leaking exhaust gaskets is essential for maintaining your Porsche’s performance, efficiency, and emissions compliance.
Key Benefits:
- Restores
proper exhaust sealing and flow efficiency.
- Reduces
exhaust noise and prevents gas leaks.
- Improves performance and throttle response.
- Prevents
damage to manifolds, sensors, and nearby parts.
- Crafted from high-grade composite or metal-reinforced materials.
- Exact-fit design for Porsche 911, Cayman, Boxster, Panamera, Macan and more.
Whether you’re rebuilding your exhaust system or performing routine maintenance, new gaskets ensure reliable sealing and long-term durability.
Highlights:
- Precision-engineered exhaust gaskets for all Porsche models.
- High-temperature, corrosion-resistant materials for durability.
- Ensures a tight, leak-free exhaust seal.
- Improves performance and emissions control.
- Perfect fit for performance and restoration projects.
- Essential for smooth, quiet, and efficient exhaust operation.
