The OE Match Rear Exhaust Mounting Kit is a complete hardware set designed to replace worn or missing mounting components for the rear exhaust system on the Porsche 997. It includes the essential rubber hangers, brackets, bolts, and insulators needed to restore proper exhaust support and alignment.
Fits:
Porsche 997 3.6L-3.8L 2005-08 (not Turbo/GT2)
Kit included:
2x Pipe Connector, 55x58.5x75mm, stainless steel

4x Lock nut, M8x1.25
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

Whether you're replacing tired heat exchangers, installing a new exhaust system or carrying out a concours-quality restoration, fitting new mounting hardware ensures every component is correctly secured while reducing the risk of vibration, exhaust leaks and premature hardware failure.
What Does the Heat Exchanger Mounting Kit Do?
The heat exchanger mounting kit provides the fixings needed
to attach the heat exchangers securely to the engine and exhaust system. It
plays an important role by:
- Securing the heat exchangers to the engine.
- Maintaining correct exhaust alignment.
- Supporting efficient cabin heating performance.
- Reducing vibration and unwanted movement.
- Helping maintain leak-free exhaust joints.
- Allowing for normal expansion and contraction as exhaust temperatures change.
Correct mounting hardware is essential for maintaining both exhaust efficiency and the performance of the Porsche heating system.
Why Do Heat Exchanger Mounting Kits Fail?
The mounting hardware operates in an extremely demanding
environment, exposed to continuous heat, moisture and vibration. Over time,
components can fail due to:
- Corrosion caused by road salt and moisture.
- Heat cycles weakening fasteners.
- Rusted or seized nuts and bolts.
- Fatigue caused by engine vibration.
- Damage during previous exhaust repairs.
- Age-related deterioration after decades of service.
As the hardware deteriorates, the heat exchangers can loosen, resulting in exhaust leaks, rattles, poor alignment and additional stress on surrounding components.
When Should the Heat Exchanger Mounting Kit Be Replaced?
The mounting hardware should be inspected whenever the
exhaust or heat exchangers are removed. Replacement is recommended if you
notice:
Rusted
or seized fasteners.
Most Porsche specialists recommend fitting a new mounting kit whenever new heat exchangers are installed, ensuring reliable installation and avoiding the reuse of weakened or corroded fixings.

The kit typically includes high-quality fasteners, clamps, nuts, bolts, washers and sealing hardware where applicable, all manufactured from corrosion-resistant materials capable of withstanding the extreme temperatures and harsh operating conditions of the exhaust system. It is the ideal solution when replacing worn or corroded original fittings during exhaust repairs or upgrades.
What This Product Does:
- Provides the essential hardware required for pre-silencer or intermediate exhaust installation.
- Secures exhaust components safely and correctly.
- Maintains proper exhaust alignment.
- Helps create leak-free exhaust connections.
- Replaces worn, seized or corroded original mounting hardware.
- Reduces vibration and movement within the exhaust system.
- Simplifies exhaust servicing and installation.
- Forms an essential part of a professional exhaust repair or replacement.
Symptoms Of Wear Or Failure:
- Exhaust blowing or gas leaks.
- Loose or misaligned exhaust components.
- Rattling or knocking noises from the exhaust system.
- Corroded or seized nuts, bolts or clamps.
- Broken or missing fixing hardware.
- Increased exhaust vibration.
- Difficulty securing replacement exhaust components.
- Premature gasket wear caused by loose joints.
- Excessive exhaust movement during driving.
- Visible rust or deterioration of mounting components.
Why Replacement Matters:
- Exhaust mounting hardware is continuously exposed to extreme temperatures, moisture, road salt and vibration. Over time, these conditions can cause fasteners to corrode, seize or lose their clamping force, making it difficult to achieve a secure and leak-free installation when replacing exhaust components.
- Reusing old hardware may result in poor alignment, exhaust leaks, unwanted vibration and premature failure of newly installed exhaust parts. Damaged or weakened fixings can also make future servicing more difficult and increase the likelihood of broken studs or seized fasteners.
- Replacing all associated mounting hardware during exhaust repairs ensures a secure installation and helps maximise the lifespan of the exhaust system. The OE Match Mounting Kit provides factory-style fitment, durable corrosion-resistant components and dependable long-term performance, helping maintain the reliability, refinement and performance expected from your Porsche.
