This OE Match exhaust seal ring is a replacement gasket ring used between the heat exchanger and cylinder head on Porsche 964 Turbo models. It is designed to match the original sealing function and provide a secure, gas-tight connection in the exhaust system
Sold individually, 3 required per side / 6 required per vehicle
Fits:
Porsche 964 Turbo 1991 - 1993
Diagram ref no 2
The seal ring creates a tight seal at the heat exchanger connection, helping prevent exhaust gases from escaping before they enter the rest of the exhaust system. A correct seal supports proper exhaust flow, reduces unwanted noise, and helps maintain engine performance.
Functions
• Seals the connection between the heat exchanger and cylinder head
• Helps prevent exhaust gas leaks
• Supports correct exhaust flow and back pressure
• Reduces ticking, blowing, or leak-related exhaust noise
• Helps maintain turbocharged engine efficiency
• Provides an OE Match replacement for the original exhaust seal ring
• Suitable for heat exchanger removal, replacement, or exhaust system service
Exhaust seal rings are exposed to extreme heat, pressure, vibration, and corrosion. Over time, the original ring can flatten, crack, burn through, or lose its sealing ability. A failed seal ring can cause exhaust leaks, ticking noises, fumes, poor sealing at the heat exchanger, and reduced exhaust system efficiency. Replacing the seal ring helps restore a tight, reliable exhaust connection.
When to replace
• The heat exchangers have been removed or replaced
• There is an exhaust leak at the heat exchanger connection
• A ticking or blowing noise is heard from the exhaust/head area
• The old seal ring is crushed, cracked, burnt, corroded, or missing
• Exhaust fumes or soot marks are visible around the joint
• Engine or turbo exhaust work is being carried out
• As preventative replacement during exhaust system reassembly

Exhaust seal ring is designed to replicate the original gasket’s fit and durability, it ensures a gas-tight seal between the exhaust manifold or heat exchanger and the cylinder head—restoring quiet, efficient performance.
Fits:
Porsche 964 C2 / C4 / Carrera RS 1989-94
Porsche 993 Carrera / Turbo 1995-98

• Seals the connection between the exhaust header / heat exchanger and the engine, preventing exhaust gas leaks
• Helps maintain correct back-pressure, avoids losing efficiency, and ensures proper exhaust flow
Over time, the original seal ring can become brittle, corroded, or compressed, causing exhaust leaks, noise, and potential loss of performance. Installing an OE-Match ring restores a tight, gas-proof seal, helping preserve exhaust integrity and efficiency.
