Bosal 135-579 End Silencer

BOSAL 135-579 End Silencer

The BOSAL 135-579 End Silencer is a high‑performance exhaust component designed to fit seamlessly into the rear exhaust system of a wide range of European vehicles, particularly those from the Citroën and Peugeot families. This silencer delivers superior noise reduction while maintaining optimal engine breathing, ensuring that your vehicle remains compliant with stringent emission regulations without compromising on performance.

Key Design Features

• Precision Machining: Each unit is manufactured using advanced CNC machining techniques to guarantee exact dimensional tolerances. This precision ensures a perfect fit onto the exhaust manifold and downstream piping, eliminating leaks and reducing backpressure.
• Durable Construction: The silencer body is forged from high‑strength steel alloy that resists corrosion and withstands the harsh thermal environment of the exhaust system. Protective coatings further enhance longevity under extreme operating conditions.
• Optimized Baffle System: Internally, a series of strategically placed baffles disrupt sound waves, converting them into heat energy. This design not only lowers noise levels but also improves exhaust flow efficiency.
• Heat‑Resistant Gasket: A specially engineered gasket seals the connection between the silencer and the exhaust pipe, preventing heat transfer to surrounding components and ensuring a tight seal throughout the vehicle’s lifespan.

Compatibility Overview

The BOSAL 135-579 is engineered for a broad spectrum of models. Its universal mounting design allows it to be installed on:

• Citroën C2, C3 I, and C3 Pluriel – models ranging from the early 2000s through the mid‑2010s.
• Peugeot 1007 and 2008 – both petrol and diesel variants.
• Other compatible vehicles that share similar exhaust manifold dimensions, including certain Ford, Dacia, and Lancia models.

For exact fitment, consult the vehicle’s service manual or BOSAL’s official part number cross‑reference guide. The silencer is available in both left‑hand drive (LHD) and right‑hand drive (RHD) configurations to accommodate global markets.

Installation Procedure

1. Preparation: Warm the engine to operating temperature to ensure accurate measurements. Disconnect the battery for safety.
2. Remove Existing Silencer: Loosen and remove the mounting bolts that secure the current exhaust tip or silencer. Carefully detach the old unit, noting any retaining clips or seals that may need replacement.
3. Clean the Mounting Surface: Use a wire brush to remove rust, scale, and debris from the exhaust pipe’s outer surface where the BOSAL will attach.
4. Apply Gasket: Place the heat‑resistant gasket onto the pipe. Ensure it sits flush with the mounting flange.
5. Attach Silencer: Position the BOSAL 135-579 over the gasket and align the bolt holes. Hand‑tighten all bolts before using a torque wrench to achieve the manufacturer’s specified torque sequence (typically 20–25 Nm).
6. Check for Leaks: After installation, start the engine and inspect the connection point for any exhaust leaks or unusual noises.

Performance Benefits

• Noise Reduction: The silencer’s advanced acoustic design reduces tailpipe noise by up to 10 dB compared to stock units, providing a quieter driving experience without sacrificing engine sound.
• Improved Fuel Efficiency: By minimizing backpressure and optimizing exhaust flow, the BOSAL 135-579 can contribute to marginal gains in fuel economy, especially under high‑load conditions.
• Enhanced Durability: The robust construction resists cracking and warping even after prolonged exposure to high temperatures, ensuring consistent performance over thousands of miles.
• Emission Compliance: The silencer’s design helps maintain exhaust gas temperature within optimal ranges for catalytic converter efficiency, aiding in meeting Euro 4/5 emission standards.

Maintenance Tips

Although the BOSAL 135-579 is engineered for long‑term reliability, routine checks can extend its service life:

• Visual Inspection: Periodically inspect the silencer for signs of corrosion or physical damage. Replace immediately if any cracks are detected.
• Gasket Replacement: Every 30,000–40,000 km, consider replacing the gasket to prevent heat transfer and maintain a tight seal.
• Cleaning: Use a non‑abrasive cleaner to remove soot buildup from the exterior. Avoid harsh chemicals that could degrade the protective coating.
