Product Information

The OE Match exhaust sealing ring gasket forms the seal at the wastegate-to-muffler connection on the Porsche Turbo exhaust assembly. It is a replacement sealing component for repairs involving a leaking joint or removal and refitting of the connected exhaust parts.

Fits

  • Porsche 911 Turbo (1978 to 1989) with engine code M930.60/66/68
  • Porsche 924 Turbo (1976 to 1985)
  • Porsche 944/2 Turbo/Turbo S (1985 to 1991) with engine code M44.50/51/52

    Check fitment for your specific vehicle (model, year, engine) before ordering.

    What Is This Part?

This ring-shaped gasket is the sealing element between the mating sections of the wastegate exhaust connection. It works with the joint's retaining hardware to close the connection when the exhaust parts are correctly seated and secured. Its role is to seal the joint rather than support the weight of the exhaust. When carrying out repairs, inspect the adjoining pipework, sealing seats and fixings as well as the gasket itself.

What Does This Part Do?

  • Seals the connection: Closes the sealing interface between the adjoining exhaust components.
  • Contains exhaust gas: Helps prevent gas escaping through the joint when correctly fitted.
  • Works with the retaining hardware: Provides the sealing element within the secured exhaust connection.

    Why Replace This Part?

Replace the gasket if inspection confirms that it is damaged, distorted or no longer sealing correctly. Blowing or ticking noises and soot marks around the connection are reasons to inspect the joint, but they do not establish that the gasket alone is responsible.

A replacement gasket should be fitted against sound, correctly aligned mating surfaces. Loose or damaged fixings, deteriorated pipe ends and poor seating also need attention; replacing the seal alone will not correct those faults. During dismantling, assess the condition of the removed ring before deciding whether it is suitable for refitting.

When to Replace This Part?

  • Visible damage: The ring is split, distorted or has damaged sealing faces.
  • Confirmed joint leakage: Inspection identifies exhaust gas escaping at this sealing connection.
  • Soot around the joint: Deposits indicate a possible leak that needs investigation.
  • Poor seating: The ring cannot sit correctly after the mating surfaces and alignment have been checked.
  • Removal damage: The gasket is damaged while separating the exhaust connection.

    Where Is This Part Fitted?

Location: At the wastegate-to-muffler exhaust connection on the applicable assembly. Confirm the joint arrangement for the specific model before dismantling or ordering associated hardware.

Product Summary

  • Product: Exhaust sealing ring gasket.
  • Brand: OE Match.
  • Purpose: Seals the applicable wastegate exhaust connection.

About Brackets / Clamps / Straps

Exhaust Mounting Brackets, Straps & Clamps – Secure, Silent & Strong

A Porsche exhaust system relies on more than just pipes and silencers — it’s held together by a network of mounting brackets, straps, and clamps that keep everything securely in place. These essential components absorb vibration, maintain correct alignment, and prevent stress or damage to exhaust pipes and mufflers.

At Design911, we stock a full range of exhaust mounting hardware, including brackets, hangers, straps, clamps, gaskets, and fasteners, all designed for long-lasting durability and a perfect fit. Built from high-strength stainless steel and corrosion-resistant materials, these components ensure your exhaust system remains properly supported and free from unwanted noise or movement.

Whether you’re performing a full exhaust replacement or a minor repair, replacing worn or rusted mounting hardware restores proper fitment and protects your Porsche’s exhaust from damage caused by vibration or misalignment.

What Do Exhaust Mounting Brackets, Straps & Clamps Do?

These small but vital parts provide the backbone for your exhaust system’s stability and integrity.

Core Functions:

  • Secure the exhaust system to the vehicle chassis.
  • Maintain correct alignment to prevent strain on joints and flanges.
  • Absorb engine vibration to reduce stress and cracking.
  • Ensure leak-free connections between pipes and silencers.
  • Prevent rattling and unwanted noise during acceleration and cornering.

Without properly functioning brackets and clamps, your exhaust can sag, vibrate, or even detach — risking costly damage and performance loss.

Why Do Exhaust Mounts and Clamps Fail?

Constant heat, vibration, and exposure to the elements make exhaust mounting components prone to wear over time.

Common Causes of Failure Include:

  • Corrosion or rust from road salt and moisture.
  • Metal fatigue caused by heat cycling and vibration.
  • Cracked or stretched straps from repeated stress.
  • Loose or broken clamps leading to exhaust leaks.
  • Rubber mount deterioration resulting in noise or exhaust movement.

Failure of these components can lead to exhaust misalignment, rattling, leaks, or premature pipe damage — issues that worsen quickly if ignored.

Why Replace Components?

Replacing worn or damaged exhaust mounting hardware ensures your Porsche’s exhaust system remains stable, quiet, and free-flowing.

Key Benefits:

  • Restores exhaust alignment and fitment.
  • Prevents damage to mufflers, pipes, and joints.
  • Eliminates rattling, vibration, and leaks.
  • Durable stainless steel and heat-resistant construction.
  • Direct-fit compatibility for all Porsche models, classic and modern.
  • Ideal for maintenance, restoration, or performance upgrades.

A secure exhaust system not only improves comfort and performance but also extends the life of other components — ensuring your Porsche remains refined and reliable.

Highlights:

  • High-quality exhaust brackets, clamps, and mounting straps.
  • Precision-engineered for Porsche fitment and durability.
  • Prevents vibration, movement, and exhaust leaks.
  • Made from corrosion-resistant stainless steel.
  • Perfect for restorations or exhaust maintenance.
  • Ensures long-term stability and quiet operation.
