Cross Over Pipe Exhaust Sealing Ring
Restore proper exhaust sealing and eliminate unwanted
exhaust leaks with Cross Over Pipe Exhaust Sealing Ring, designed
for Porsche 911 models produced between 1975 and 1989. This sealing ring is
used within the cross over pipe section of the exhaust system, creating a
gas-tight seal between connected exhaust components.
Fits:

The cross over pipe is a critical part of the air-cooled Porsche exhaust system, helping balance exhaust gas flow and directing gases efficiently through the exhaust assembly. The sealing ring ensures that exhaust gases remain contained within the system, preventing leaks that can reduce performance, increase noise and affect overall driving enjoyment.
Over time, exhaust sealing rings are subjected to extreme temperatures, vibration, pressure fluctuations and corrosion. As the seal ages, it can become compressed, brittle or damaged, leading to exhaust leaks and reduced system efficiency.
Replacing worn sealing rings whenever exhaust components are removed is essential for maintaining proper exhaust system performance and reliability.
What Does a Cross Over Pipe Exhaust Sealing Ring Do?
The exhaust sealing ring sits between mating exhaust components and creates a heat-resistant seal that prevents exhaust gases from escaping.
A properly functioning sealing ring helps:
- Maintain a leak-free exhaust system
- Ensure correct exhaust gas flow
- Reduce exhaust noise
- Support engine efficiency
- Prevent exhaust fumes escaping at joints
- Maintain correct exhaust back pressure
- Protect surrounding components from hot gas leakage
Without an effective seal, exhaust gases can escape before reaching the silencer system.
Symptoms of Wear or Failure
Exhaust sealing rings naturally deteriorate due to constant exposure to heat and vibration.
Common signs of a failing sealing ring include:
- Exhaust blowing noises
- Ticking sounds from the exhaust system
- Visible soot deposits around joints
- Increased exhaust noise
- Exhaust fumes around the vehicle
- Reduced engine efficiency
- Poor sealing after exhaust disassembly
- Signs of compression or deterioration during inspection
Even a small leak can become progressively worse if the sealing ring is not replaced.
Why Replacement Matters
Replacing a worn exhaust sealing ring helps maintain exhaust system integrity and prevents secondary damage to other exhaust components.
Benefits include:
- Restores leak-free exhaust operation
- Improves exhaust system efficiency
- Reduces unwanted exhaust noise
- Helps maintain correct exhaust flow
- Protects surrounding exhaust components
- Improves repair reliability
- Supports long-term durability
- Enhances restoration quality
For classic air-cooled Porsche 911 models, maintaining correct exhaust sealing is essential for performance, reliability and driving enjoyment.

This OE clamp is used to secure the exhaust tailpipe section in place, helping maintain correct alignment, sealing and support within the rear exhaust system.
Functions
• Secures the exhaust tailpipe connection in the correct position
• Helps maintain proper tailpipe alignment at the rear of the vehicle
• Supports a tight and stable exhaust joint
• Helps reduce exhaust movement, vibration and rattling
• Assists in keeping the exhaust outlet correctly positioned in the rear bumper area
• Suitable for cars with or without Porsche Sports Exhaust on the listed applications
The exhaust tailpipe clamp is exposed to heat, road dirt, moisture and corrosion. Over time, the clamp can weaken, rust, seize or lose clamping force, which may allow exhaust movement, poor alignment or rattling from the rear exhaust section. Replacing a worn or damaged clamp with a Genuine Porsche OE part helps restore the correct fit, support and factory-quality connection.
When to Replace
• This Part When the original clamp is corroded, cracked or damaged
• When the tailpipe section is loose or misaligned
• If there is a rattle or vibration from the rear exhaust area
• During tailpipe, silencer or rear exhaust removal/refitting
• If the clamp bolt is seized or cannot be reused
• When carrying out exhaust repairs or restoration work.

The exhaust tailpipe clamp fastens and seals the tailpipe or exhaust connection point, helping to keep the exhaust system properly aligned and leak-free. It allows exhaust sections to be joined securely without welding, making replacement or servicing easier.
Functions
• Secures the exhaust tailpipe connection in place
• Helps prevent exhaust gas leaks at the joint
• Maintains correct alignment of exhaust components
• Reduces unwanted vibration, rattling, or movement
• Supports a reliable seal between exhaust sections

Over time, exhaust clamps can corrode, weaken, stretch, or lose clamping force due to heat cycles, road debris, and exposure to moisture. A worn or damaged tailpipe clamp can cause exhaust leaks, rattling noises, poor exhaust alignment, or visible movement in the rear exhaust section. Replacing the clamp helps restore a secure exhaust connection and keeps the system operating as intended.
When to replace
• The clamp is corroded, cracked, damaged, or seized
• Exhaust gas is leaking from the tailpipe joint
• There is rattling or vibration from the rear exhaust area
• The tailpipe or exhaust outlet is loose or misaligned
• The clamp has been removed during exhaust repair and cannot be reused
• The exhaust system is being serviced, replaced, or refitted
