• 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.
