Exhaust Renault Rapid (1985-2001)

The exhaust system in the Renault Rapid is a complex assembly that includes the exhaust manifold, catalytic converter, resonator, diesel particulate filter (DPF) for diesel models, and muffler. Its main function is to evacuate burned gases from the engine cylinders to the rear of the vehicle, reduce noise, limit pollution emissions, and comply with environmental legislation. The system must be airtight for safety and efficiency.

Key specifications of some Renault Rapid exhaust components include:

• Complete exhaust (Ref: 7700018114): Length 1110 mm; fixation plate 75 x 39 mm; suitable for agricultural & utility Renault models.
• Exhaust valve (Rapid Van 1.0 42 HP petrol C1C 706): Front axle side, diameter 238 mm, solid disc type.
• Exhaust pipe (Rapid Van 1.2 54 HP petrol C1G 726): Lengths 600 mm / 536 mm; weight 1.44 kg; Ref RR-195.
• Rear muffler (ROMAX): Compatible with Renault Express/Rapid 1.2 to 1.9 engines; Ref 42 4 111.
• Exhaust pot (VEGAZ): For Rapid Kasten, Ref RS-258, new condition.

These parts typically fit utility versions (Kasten/Van) with petrol or diesel engines up to 1.9 L displacement. Compatibility should always be checked against engine type and model year.

The Renault Rapid exhaust system should be inspected every 20,000 km to detect leaks, vibrations, or faults that might cause failure in vehicle inspection tests.

For diesel models fitted with DPF (diesel particulate filter), a natural regeneration is recommended by driving at engine speeds around 3000 rpm on a highway for several tens of kilometers at least once a month.

Replacement of the DPF is necessary if it becomes clogged beyond cleaning.

Replacement of the exhaust system is advised in cases of:

• Excessive noise or loss of engine power.
• Failure to meet environmental regulations and to pass vehicle technical control inspections.
• Presence of dangerous vibrations or detachment of exhaust components caused by corrosion or damage.

Because exhaust pipes can be tightly corroded or stuck together, it is recommended to replace the entire exhaust line except for the catalytic converter and flexible pipe where possible. This work should be done by a professional with proper tools, such as authorized Renault workshops.

The exhaust system is composed of the following main elements:

• Exhaust manifold
• Catalytic converter (to reduce harmful emissions)
• Resonator or relaxation pot
• Diesel Particulate Filter (DPF) on diesel engines
• Muffler (silencer) to reduce noise
• Connecting pipes, clamps, and flanges

These parts work together to ensure proper gas evacuation, noise reduction, and emission control.

To maintain the diesel particulate filter (DPF) efficiently and avoid clogging:

• Drive regularly at sustained engine speeds (about 3000 rpm) on highways to allow natural regeneration of the filter.
• Avoid short trips that prevent the engine from reaching optimal operating temperature.
• Replace the DPF when it is irreversibly clogged.

Following these practices helps preserve the filter’s function and mechanical integrity.

Quality exhaust parts and detailed technical information for the Renault Rapid range can be sourced from specialized European suppliers offering original or manufacturer-quality components compliant with standards.

• Look for parts compliant with manufacturer specifications and with proper certifications like E24-103R.
• Consult official Renault technical documentation and authorized service centers for expert advice.
• Use exact vehicle data (motorization, model year) to verify parts compatibility before purchase.

Choosing quality parts ensures reliability, long life, and environmental compliance for your vehicle.
