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.
