Information
Exhaust sleeve catalytic converter to U-Bend
Genuine Porsche exhaust clamp - also called a clamping sleeve - It is used where the catalytic converter connects to the next section of exhaust (U-bend/silencer pipe) on Porsche 986 Boxster models.
Sold as: Single clamp (two may be required per complete joint).
Fits:
Porsche 986 Boxster 1997 - 2004
Diagram ref no 15
The exhaust clamp helps secure and seal the exhaust connection between the catalytic converter and adjoining exhaust pipe sections. Under normal operation, exhaust components heat up, cool down, and experience vibration; this clamp maintains a tight mechanical joint, preventing exhaust leaks, excessive movement, and noise. Genuine Porsche clamps are engineered with durable materials that withstand heat, corrosion, and vibration as intended by the factory design.
Function:
• Secures exhaust junctions: Holds exhaust piping tightly together
• Prevents exhaust leaks: Maintains a sealed joint at critical interfaces
• Resists corrosive conditions: Designed for high-temperature exposure
• Ensures proper exhaust alignment: Reduces noise, rattles, and stress on mounts
As part of the exhaust system hardware, proper clamp integrity helps the entire exhaust assembly function smoothly and reliably across varying conditions.
Exhaust clamps are exposed to extreme temperatures, road salts, and moisture - conditions that accelerate corrosion and fatigue. Over time, original clamps can weaken, rust, or lose clamping force, leading to:
• Exhaust leaks Increased noise or vibration
• Poor exhaust alignment
• Potential damage to adjacent components
Using a Genuine Porsche clamp ensures the joint is restored to factory-spec tightness, maintaining proper exhaust pressure sealing and alignment as originally designed.
When to replace. Replace the exhaust clamp when:
• You are servicing or refitting the exhaust system
• The original clamp shows rust, deformation, or breaks
• You hear exhaust leaks or unusual noise at the catalytic converter junction
• The clamp no longer holds the pipes firmly in place

Information
Exhaust System Clamp Set.
Diagram Ref No 4, 8, 9, 10
Exhaust clamps play an important role in keeping the exhaust system stable under heat expansion, vibration, and engine movement. A worn or corroded clamp can cause exhaust leaks, rattles, poor fitment, or misalignment—especially on performance or stainless exhaust systems where correct sealing is essential.
This clamp set is ideal when fitting a new exhaust, replacing damaged clamps, or refreshing fixings during exhaust maintenance.

A worn or corroded clamp can cause exhaust leaks, rattles, poor fitment, or misalignment—especially on performance or stainless exhaust systems where correct sealing is essential.
This clamp set is ideal when fitting a new exhaust, replacing damaged clamps, or refreshing fixings during exhaust maintenance.
What This Product Does:
- Secures exhaust joints and pipe connections
- Maintains proper alignment of exhaust components
- Helps prevent exhaust gas leaks at connection points
- Reduces vibration movement and exhaust rattles
- Supports safe, reliable long-term exhaust system operation
- Makes exhaust assembly replacement or servicing easier and cleaner
Symptoms Of A Failing Exhaust Clamp:
- Exhaust blowing / hissing sound near a joint
- Rattling or knocking noises from underneath the car
- Visible soot marks around pipe joins (sign of leaking gases)
- Loose exhaust sections or misaligned tailpipes
- Corroded, seized, or snapped clamp hardware
- Exhaust fumes smell stronger than normal (possible leak
Why Replacement Matters:
- Prevents exhaust leaks that affect performance and sound quality
- Reduces vibration and rattles for a smoother driving experience
- Protects surrounding components from heat and gas leakage
- Ensures correct exhaust fitment, sealing, and support
- Avoids clamp failure during removal/refitting (especially if original fixings are rusted or seized)
