Information
Exhaust sleeve catalytic converter to u-bend.
OE Match exhaust clamping sleeve / exhaust clamp designed to secure and join exhaust components in the Porsche Boxster 986 (1997–2004) exhaust system. It functions as a durable connector between the catalytic converter and U-bend / silencer pipes, helping maintain a tight exhaust joint.
Sold as: Single clamp (two may be required per complete joint).
Fits:
Porsche 986 Boxster 1997 - 2004
Diagram ref no 15
The exhaust clamping sleeve secures two sections of the exhaust - typically where the catalytic converter outlet meets the U-bend or silencer pipe. It ensures a firm, vibration-resistant connection that prevents exhaust leakage, reduces noise, and supports proper exhaust routing. A good clamp helps the exhaust stay aligned under heat expansion and road vibration, reducing stress on nearby hangers and components.
Function:
• Joins exhaust sections securely (catalytic converter to U-bend/silencer)
• Prevents exhaust leaks by maintaining a tight pipe connection
• Absorbs movement and heat expansion without loosening
• Supports proper alignment of the exhaust system under operating loads.
Without a sound clamp, exhaust joints can leak hot gases, which leads to reduced performance, unwanted noise, and possible component wear.
Exhaust clamps live in a high-heat, corrosive environment, and over time the original sleeve can:
• Corrode or rust, reducing clamp effectiveness
• Lose clamping force from heat cycling
• Allow exhaust leaks at pipe connections
• Cause excess exhaust noise or vibration.
Replacing worn or damaged clamps with OE Match units helps ensure a tight seal, prevents exhaust gas escape, and protects other exhaust components from undue movement or stress.
When to replace. Replace this exhaust clamp when:
• You remove or refit the exhaust system (e.g., catalytic converter or silencer)
• The existing clamp is corroded, bent, or stretched

Information
Exhaust U-tube clamp (52mm)
OE Match exhaust U-tube clamp used to secure the exhaust connecting pipe at the U-bend (U-tube) on Porsche 986 Boxster applications.
Sold each, 2 required per vehicle.
Fits:
Porsche 986 Boxster 2.5L / 2.7L / 3.2L 1997 - 2004
Diagram ref no 13
It locks the exhaust joint together at the connecting pipe/U-bend interface, maintaining alignment and helping prevent exhaust leaks, vibration, and movement under heat expansion. A fresh clamp is especially important after exhaust removal, where old clamps often seize or deform and can’t be reused reliably.
Function:
• Provides secure clamping force at the U-tube/connecting pipe joint
• Helps maintain a tight, leak-resistant seal under heat cycling
• Supports proper exhaust alignment to reduce rattles and stress on joints
Exhaust clamps live in a harsh environment and commonly rust, seize, and become impossible to loosen without damage. Replacing the clamp during exhaust work helps ensure the joint reseals properly, avoids leaks and rattles, and prevents wasted time fighting corroded hardware.
When to replace:
• When removing/refitting the U-bend or connecting pipe
• If the clamp is corroded, seized, stretched, or deformed
• If you have exhaust blowing/leak noise at the joint
• If bolts/threads are damaged or won’t torque correctly
