Product Information

Exhaust Gasket Kit

Restore proper exhaust sealing and eliminate unwanted exhaust leaks with this comprehensive Exhaust Gasket Kit for Porsche 911 3.2 Carrera models produced between 1984 and 1989. Designed for air-cooled Porsche engines, this complete kit contains all the key gaskets required when servicing, rebuilding or replacing exhaust system components.

Fits:

Porsche 911 1984-1986 3.2L
Porsche 911 1987-1989 3.2L G50

These gaskets create critical gas-tight seals between exhaust components, preventing exhaust gases from escaping before reaching the silencer system. Proper sealing helps maintain engine efficiency, exhaust performance and correct operation of the entire exhaust system.

The kit includes:

6 x Heat Exchanger to Cylinder Head Gaskets
2 x Heat Exchanger Cross Pipe / Pre-Silencer Gaskets
2 x Pre-Silencer to Rear Silencer Gaskets

Whether carrying out an exhaust repair, heat exchanger replacement or full restoration project, replacing old exhaust gaskets is essential to ensure long-term reliability and optimum performance.

What Does an Exhaust Gasket Kit Do?

Exhaust gaskets are designed to seal the connections between exhaust system components, preventing exhaust gases from escaping under pressure.

A properly functioning gasket system helps provide:

Leak-free exhaust operation Correct exhaust gas flow
Reduced exhaust noise
Improved engine efficiency
Proper back pressure characteristics
Reduced risk of exhaust fumes entering the cabin
Reliable long-term exhaust performance

Because exhaust systems operate under extreme heat and pressure, gasket condition is critical to maintaining proper sealing.

Symptoms of Exhaust Gasket Wear or Failure

Exhaust gaskets are constantly exposed to thermal cycling, vibration and corrosive exhaust gases. Over time they can deteriorate, compress, crack or fail.

Common symptoms include:

Exhaust blowing noises
Ticking or tapping sounds on start-up
Increased exhaust noise
Exhaust fumes around the engine bay
Reduced engine performance
Soot deposits around exhaust joints
Exhaust smell entering the cabin
Visible gasket deterioration during inspection
Poor sealing after exhaust system removal

In many cases, exhaust leaks become progressively worse if damaged gaskets are not replaced.

Why Replacement Matters

Replacing exhaust gaskets whenever exhaust components are removed is considered best practice maintenance.

Benefits include:

Restores leak-free exhaust operation
Eliminates exhaust gas leaks
Improves engine efficiency
Reduces unwanted exhaust noise
Protects surrounding engine components
Helps maintain correct exhaust flow characteristics
Supports safe vehicle operation
Improves reliability of exhaust repairs

For classic air-cooled Porsche 911 models, maintaining a properly sealed exhaust system is essential for both performance and driving enjoyment.

About Exhaust Gaskets

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.
