Exhaust Clamp for Cross Over Pipe - Clamp Made Out of 2 Halves
Maintain a secure and leak-free exhaust system with Exhaust
Clamp, designed for use on the cross over pipe of Porsche 911
models produced between 1975 and 1989. Manufactured from mild steel, this clamp
consists of two matching half sections that bolt together around the exhaust
pipe connection, providing the clamping force required to secure and seal the
joint.

The cross over pipe forms an important part of the air-cooled Porsche exhaust system, helping direct exhaust gases between engine banks and associated exhaust components. The clamp plays a critical role in maintaining correct pipe alignment while preventing movement, vibration and exhaust leaks.
Over time, original exhaust clamps can become corroded, weakened or damaged due to repeated heat cycles, moisture exposure and road contamination. Replacing worn clamps helps ensure reliable exhaust system operation and supports long-term durability.
What Does an Exhaust Clamp Do?
An exhaust clamp secures adjoining exhaust components together while helping maintain a tight and stable connection.
A properly functioning exhaust clamp helps:
- Secure exhaust pipe joints
- Maintain correct pipe alignment
- Reduce exhaust movement and vibration
- Help prevent exhaust gas leaks
- Support gasket sealing performance
- Improve exhaust system reliability
- Protect connected exhaust components
Without sufficient clamping force, exhaust joints can loosen and allow gases to escape.
Symptoms of Wear or Failure
Exhaust clamps operate in one of the harshest environments on the vehicle and are constantly exposed to heat, corrosion and vibration.
Common signs that replacement may be required include:
- Visible rust or corrosion
- Cracked or weakened clamp sections
- Loose exhaust joints
- Exhaust blowing noises
- Rattling from the exhaust system
- Exhaust leaks around pipe connections
- Soot deposits around clamp areas
- Distorted or damaged clamp halves
- Difficulty maintaining correct torque
A failing clamp can allow excessive movement within the exhaust system, leading to leaks and additional component wear.
Why Replacement Matters
Replacing a worn exhaust clamp helps maintain exhaust system integrity and prevents unnecessary stress on surrounding components.
Benefits include:
- Restores secure pipe connections
- Reduces exhaust leaks
- Improves exhaust system stability
- Minimises vibration and rattles
- Helps maintain proper exhaust flow
- Protects connected pipes and silencers
- Supports reliable long-term performance
- Improves repair and restoration quality
For classic air-cooled Porsche 911 models, replacing ageing exhaust hardware is an important part of maintaining both performance and reliability.

The OE Match Exhaust Rubber Mounting is a replacement flexible exhaust support used on selected classic Porsche transaxle models.
Fits:
Diagram Ref No 15
The rubber mounting forms part of the exhaust support system, helping suspend the exhaust securely from the vehicle while isolating vibration and allowing a controlled amount of movement as the exhaust heats, cools and moves with the drivetrain.
A healthy exhaust mounting helps keep the exhaust correctly positioned beneath the vehicle while reducing vibration and noise transferred into the body structure.
What This Product Does:
The exhaust system becomes hot during operation and expands as temperature increases.
It also moves slightly in response to:
- Engine and drivetrain movement
- Road vibration
- Suspension movement
- Thermal expansion
- Changes in vehicle load
The rubber exhaust mounting provides a flexible connection between the exhaust system and the vehicle structure.
Its functions include:
- Supporting the weight of the exhaust
- Maintaining correct exhaust positioning
- Absorbing vibration
- Reducing noise transmitted into the chassis
- Allowing controlled exhaust movement
- Reducing stress on exhaust pipes and joints
- Helping maintain clearance from surrounding components
- Preventing excessive exhaust movement over bumps
Without compliant rubber mountings, vibration and movement could place additional stress on rigid exhaust components.
Symptoms Of Wear Or Failure:
Common signs of a deteriorated exhaust rubber mounting include:
Some exhaust noise can also be caused by loose heat shields, broken brackets or damaged internal muffler components, so the complete mounting system should be inspected.
Why Replacement Matters:
A worn exhaust mount may appear to be a minor issue, but continued use can allow excessive movement of relatively heavy exhaust components.
This may contribute to:
- Cracked exhaust pipes
- Failed welds
- Damaged exhaust joints
- Loose clamps
- Broken mounting brackets
- Exhaust contact with the vehicle body
- Increased vibration and rattling
- Poor exhaust-tip alignment
- Premature failure of neighbouring mountings
Replacing a deteriorated mount restores proper support and reduces unnecessary stress on the rest of the exhaust system.
