Exhaust Gaskets
The Genuine Porsche Exhaust Gasket 477253115E is a replacement sealing component designed for the connection between the exhaust manifold and downpipe on compatible left-hand-drive (LHD) Porsche applications.
Fits:
- Porsche 924 2.0L 1976-79
- Porsche 924 2.0L 1980-85
Diagram Ref No 11
This gasket creates a gas-tight seal at an important exhaust-system joint, preventing hot exhaust gases from escaping before they continue through the downpipe and the rest of the exhaust system.
Constant exposure to extreme temperatures, exhaust gases and repeated heating and cooling cycles can cause an old gasket to deteriorate, compress or burn through. Replacing a failed gasket helps restore a properly sealed exhaust connection, reduce unwanted exhaust noise and prevent hot gases leaking around the manifold-to-downpipe joint.
What This Product Does:
The exhaust gasket sits between the mating surfaces of the exhaust manifold and downpipe, creating a seal when the components are secured together.
Exhaust gases leave the engine at high temperature and pressure. These gases must remain contained within the exhaust system as they travel away from the engine.
The gasket helps:
- Create a gas-tight manifold-to-downpipe connection
- Prevent exhaust gases escaping through the joint
- Reduce unwanted exhaust noise
- Maintain proper exhaust-system integrity
- Protect surrounding components from escaping hot gases
- Prevent exhaust fumes leaking from the connection
- Maintain a secure seal despite repeated thermal expansion and contraction
Although relatively small, the gasket plays an important role in keeping the exhaust system correctly sealed.
Symptoms Of Wear Or Failure:
A deteriorated manifold-to-downpipe gasket can allow exhaust gases to escape through the connection.
Common symptoms may include:
- Ticking, tapping or blowing noise from the exhaust joint
- Increased exhaust noise
- Hissing or puffing sounds during acceleration
- Exhaust fumes or odour around the engine or underside of the vehicle
- Black soot deposits around the manifold-to-downpipe connection
- Visible signs of exhaust gas leakage
- Reduced exhaust-system sealing
- Noise that becomes more noticeable under load
- Heat damage or discolouration around the leaking joint
- Engine or emissions-related faults where applicable
A small leak may initially only be noticeable when the engine is cold or under acceleration.
Why Replacement Matters:
A leaking exhaust gasket should not be ignored.
Replacing a worn or damaged manifold-to-downpipe gasket helps:
- Restore a properly sealed exhaust connection
- Prevent hot exhaust gases escaping from the joint
- Reduce blowing, ticking and hissing noises
- Prevent soot accumulation around the connection
- Protect nearby components from concentrated exhaust heat
- Reduce the possibility of exhaust fumes entering areas where they should not
- Maintain correct exhaust-system operationRestore a cleaner and quieter exhaust system
A deteriorated gasket can progressively worsen as hot gases erode the sealing area.

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.
