• Includes connectors, plates, gaskets, nuts, bolts, and lock nuts
• Helps prevent exhaust leaks and reduces noise
• Supports proper alignment and vibration resistance
• design for direct, no-modification installation
The exhaust mounting hardware on older vehicles can suffer from corrosion, wear, or loosening due to repeated heat cycling and road conditions. Loose or deteriorated mounting parts can lead to exhaust leaks, noise, reduced performance, or even damage to catalytic converters and adjacent components. Replacing them with an OE Match mounting kit restores secure, leak-free connections and maintains the integrity of the catalytic converter and wider exhaust system.
When to replace:
• During catalytic converter or exhaust system replacement
• Hardware shows corrosion or stripped threads
• Noticeable exhaust leaks or rattles under acceleration
• After vibration or loosening of exhaust joints
• Routine service or restoration work

Everything required to securely install compatible catalytic converter or dummy catalytic pipe assemblies.
What Does the Mounting Kit Do?
The mounting kit secures the catalytic converter or replacement pipework to the exhaust system while providing a gas-tight seal between connecting flanges.
Its functions include:
- Securing the catalytic converter or replacement pipes.
- Creating leak-free exhaust joints.
- Maintaining correct exhaust alignment.
- Preventing exhaust gas leaks.
- Reducing vibration and movement.
- Ensuring reliable long-term installation.
Replacing the fitting hardware whenever exhaust components are changed helps ensure maximum durability and sealing performance.
Why Replace the Mounting Hardware?
Exhaust mounting hardware operates in one of the harshest
environments on the vehicle, exposed to:
- Extreme exhaust temperatures.
- Road salt and moisture.
- Corrosion.
- Thermal expansion and contraction.
- Rusted or seized fasteners.
- Exhaust vibration.
Attempting to reuse old hardware often results in broken bolts, poor sealing or premature exhaust leaks.
Signs Your Mounting Kit Should Be Replaced
Replacement is recommended if you notice:
- Rusted clamps.
- Corroded nuts or bolts.
- Damaged exhaust gaskets.
- Exhaust leaks.
- Loose catalytic converter connections.
- Broken or seized fixings.
- Exhaust rattles after installation.
Installing new hardware during every exhaust repair helps ensure a secure and reliable fit.
