This OE Match exhaust O-ring is a replacement sealing ring for the tail pipe connection on Porsche 964 models. It is designed to match the original-style fitment and function, helping provide a secure seal within the rear exhaust tail pipe assembly.
Sold individually
Fits:
Porsche 964 C2 / C4 1989 - 1994
Diagram ref no 6
The exhaust O-ring helps seal the joint at the tail pipe connection, reducing the risk of exhaust gas leaks and supporting correct exhaust system fitment. A good sealing ring helps maintain proper exhaust flow, reduce unwanted blowing noises, and support a secure tail pipe installation.
Functions
• Replaces the exhaust O-ring for the tail pipe
• Helps seal the tail pipe connection
• Supports correct exhaust gas flow
• Helps reduce exhaust leaks and unwanted noise
• Supports secure exhaust tail pipe fitment
• Replaces worn, flattened, cracked, missing, or heat-damaged original O-rings
• OE Match replacement for Porsche 964 exhaust repair.
Why Replace This Part?
Exhaust sealing rings are exposed to high heat, vibration, exhaust gases, corrosion, and repeated thermal cycling. Over time, the O-ring can flatten, harden, crack, perish, or lose its sealing ability. A failed exhaust O-ring may cause exhaust leaks, blowing noises, fumes, poor tail pipe fitment, or reduced exhaust system sealing. Replacing the O-ring helps restore a secure and reliable tail pipe seal.
When to Replace This Part
• The tail pipe has been removed or replaced
• Exhaust blowing or leakage is present at the tail pipe joint
• The original O-ring is flattened, cracked, brittle, or missing
• Exhaust fumes or noise are noticeable around the rear exhaust area
• Exhaust system service or restoration is being carried out
• Tail pipe fitment is loose or not sealing correctly
• Preventative replacement is being carried out during exhaust repair.
Where it fits on the car
This O-ring fits at the tail pipe connection within the exhaust system on Porsche 964 models. It forms part of the rear exhaust sealing arrangement.

Fits:
Porsche 997 3.6L-3.8L 2005-08 (not Turbo/GT2)
Kit included:
2x Pipe Connector, 55x58.5x75mm, stainless steel

This product is a comprehensive OE Match rear exhaust mounting kit for the Porsche 997 family. Over time, exhaust mounting rubbers, brackets, and associated fixings can deteriorate due to heat cycling, vibration, and exposure to corrosive elements. This kit brings together all the normal wear components in one package, allowing a complete refresh of the rear exhaust support hardware.
Each piece in the kit has been selected or engineered to match the dimensions, materials, and load-bearing characteristics of the factory parts, ensuring correct exhaust position and reduced risk of sagging, rattling, or detachment.
Over time, rear exhaust mounting components can:
• Harden, crack, or split due to age and heat
• Corrode and weaken under road salt and moisture exposure
• Stretch or deform, allowing excessive exhaust movement
• Loosen, causing rattle, vibration, or exhaust contact with bodywork
Failing mounts can lead to:
• Exhaust system sagging
• Unwanted noises
• Metal fatigue or cracking
• Reduced ground clearance
Installing a complete OE Match rear exhaust mounting kit restores proper support, improves NVH (noise, vibration, harshness), and helps prolong the life of the exhaust system.
When to replace. Install this kit when:
• You notice exhaust sagging at the rear
• There’s excessive vibration or noise from the exhaust area
• Exhaust hangers show visible wear, cracking, or separation
• You are replacing or removing the rear exhaust system
• You’re performing a comprehensive underbody service

Why Replace Your Exhaust Clamp
- Restore a perfect, leak-free seal
- Over time, exhaust clamps can deform, corrode, or lose their clamping strength. Replacing the clamp ensures a secure joint between muffler sections, preventing exhaust leaks, restoring proper back pressure, and maintaining optimal engine performance.
- Eliminate rattles and vibration noise
- Worn or loose clamps are a common cause of rattles, buzzing, or vibration noises from the rear underside of 997 and 991 models. Installing a new clamp is often one of the quickest and most cost-effective ways to eliminate these irritating sounds.
- Factory specifications fitment for performance models
Common Issues and Failure Modes
- Corrosion and rust
- Exhaust clamps and fasteners are exposed to heat, moisture, and road salt. Over time, this can lead to corrosion or seizure, reducing clamping force and risking exhaust leaks.
- Clamp fatigue or deformation
- Repeated heat cycles and vibration can cause the clamp sleeve or bolt to distort, leading to a loose connection and exhaust blow-by.
- Incorrect fitment or short sleeves
- Noise from over-tightening
- Applying excessive clamping force can alter vibration characteristics and introduce new noises. Always follow correct installation torque and alignment procedures.
