OEM Second Cat Rubber Hanger Renault Clio 4 RS

Why Replace the Secondary Catalyst Rubber Hanger on Your Clio 4 RS?

The exhaust system on a hot hatch like the Renault Clio 4 RS endures significant thermal cycles and strong mechanical movement during aggressive driving. The catalyst rubber mount serves as a vital insulator: it suspends the second catalytic converter beneath the chassis while damping engine movements and road vibration.

What You Risk by Driving with a Worn or Torn Exhaust Hanger

Keeping a hardened, heat-damaged, or cracked rubber mount exposes your car to costly mechanical issues and compromises driving comfort:

• Underbody Knocking Noises: As the rubber sags, the exhaust line hangs lower and strikes heat shields or subframe braces over bumps and hard cornering.
• Cracks and Fractures in the Exhaust Line: If the secondary cat is no longer properly damped, torsional stress transfers directly to the piping, snapping mounting brackets or causing flange leaks.
• Accelerated Wear on Mounting Hardware: Excessive movement strains and strips the OEM retaining bolt over time, leading to loose mountings.
• Increased Cabin Vibration: Unfiltered engine vibrations transmit straight through the chassis, ruining acoustic comfort inside the vehicle.

The Quality of a Genuine Renault Sport Rubber Mount

To guarantee long-term fitment and protect your Renault Sport exhaust setup, using an authentic factory component is essential. Unlike cheap aftermarket rubber bushings that soften and stretch under exhaust heat, this genuine Renault exhaust hanger is engineered from a high-grade elastomer resistant to high temperatures, oil degradation, and aging.

Vehicle and Chassis Compatibility

This secondary catalyst hanger is specifically engineered for:

• Renault Clio 4 RS 1.6 Turbo EDC (200 hp)
• Renault Clio 4 RS Trophy 1.6 Turbo EDC (220 hp)
• Versions equipped with Sport Chassis or Cup Chassis

Frequently Asked Questions (FAQ) – Expert Maintenance Advice

How do I spot a worn secondary catalyst rubber mount?

A quick underbody inspection will reveal if the rubber shows cracking, dry rot, or oil contamination. If the exhaust system sways excessively when shaken by hand (when cold), the mount has lost its tension and needs replacing.

Should I replace the mounting bolt at the same time?

If the original bolt shows signs of corrosion or thread damage, replacing it alongside the rubber hanger is highly recommended to ensure correct torque and prevent thread seizing later on.
