Exhaust Rear Silencer Gasket.

The OE MATCH Exhaust Rear Silencer Gasket is a high-quality replacement sealing gasket designed to provide a secure, gas-tight connection between the rear silencer (muffler) and adjoining exhaust system components. Engineered to OE specifications, this gasket helps prevent exhaust leaks, maintain correct exhaust flow, and ensure efficient operation of the exhaust system.

Fits:

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50  

Manufactured from durable, heat-resistant materials, the gasket is designed to withstand extreme exhaust temperatures, pressure fluctuations, and continuous thermal cycling. It is an essential replacement component whenever the rear silencer is removed, replaced, or serviced, helping to restore the integrity of the exhaust system.

What This Product Does:

• Creates a gas-tight seal between the rear silencer and exhaust system components
• Prevents exhaust gas leaks at connection points
• Maintains proper exhaust flow and system efficiency
• Helps reduce unwanted exhaust noise
• Supports optimal engine performance and emissions control
• Withstands high exhaust temperatures and vibration

Symptoms Of Wear Or Failure:

• Exhaust blowing, ticking, or hissing noises
