BOSAL 255-448 Rubber Buffer – The Quiet Companion for Your Exhaust System

What Is the BOSAL 255‑448?

The BOSAL 255‑448 Rubber Buffer, also known as a silencer or exhaust support, is a high‑performance rubber mounting component designed to reduce vibration and noise from an automobile’s exhaust system. It serves as a flexible bridge between the exhaust pipe and the vehicle chassis, absorbing harsh engine vibrations while maintaining a secure connection.

Core Features

• Premium Rubber Construction: Made from durable, high‑temperature resistant rubber that withstands the rigors of daily driving and extreme operating conditions.
• Vibration Dampening: Engineered to isolate the exhaust system from chassis vibrations, resulting in a smoother ride and quieter cabin.
• Heat Resistance: Maintains structural integrity even at temperatures exceeding 400 °F (200 °C).
• Universal Fitment: Compatible with a wide range of vehicles including Peugeot 307, 308, Citroën C4 I, and other models that use the 1755H6 exhaust system.
• Easy Installation: Designed for quick replacement without the need for specialized tools or extensive modifications.

Material Composition & Engineering

The BOSAL 255‑448 is crafted from a proprietary blend of synthetic rubber and reinforcing fibers. This combination provides:

• High Tensile Strength: Ensures the buffer can handle repeated flexing without cracking.
• Elastic Recovery: Allows the component to return to its original shape after compression, preventing permanent deformation.
• Chemical Resistance: Protects against corrosive exhaust gases and oil residues.

Installation Guide

Installing the BOSAL 255‑448 is straightforward. Follow these steps for optimal performance:

1. Preparation: Disconnect the battery, lift the vehicle with a jack stand, and secure it safely.
2. Remove Old Buffer: Loosen the mounting bolts that hold the existing rubber buffer in place. Carefully detach the old component from the exhaust pipe and chassis.
3. Clean Surfaces: Wipe the mating surfaces on both the exhaust pipe and the mounting brackets to remove rust, oil, or debris.
4. Position New Buffer: Place the BOSAL 255‑448 between the exhaust pipe and the chassis. Align it so that the rubber side contacts the pipe and the metal side attaches to the mounting bracket.
5. Tighten Bolts: Secure the buffer with the provided bolts, tightening them in a cross‑pattern to ensure even pressure distribution.
6. Check Alignment: Verify that the exhaust pipe remains straight and that there is no undue stress on the rubber buffer.
7. Lower Vehicle & Test: Lower the car, reconnect the battery, and start the engine. Listen for any abnormal vibrations or noises; a properly installed buffer should noticeably reduce them.

Benefits of Using BOSAL 255‑448

• Reduced Cabin Noise: By absorbing vibrational energy, the buffer keeps the interior quieter, enhancing driver comfort.
• Extended Exhaust Life: Minimizing vibration reduces wear on exhaust components such as gaskets and flanges.
• Improved Vehicle Longevity: Less mechanical stress translates to fewer failures over time.
• Enhanced Driving Experience: A smoother ride with less rattling contributes to overall vehicle enjoyment.

Compatibility Overview

The BOSAL 255‑448 is engineered for a variety of models that share the same exhaust geometry. Commonly supported vehicles include:

• Peugeot 307 & 308 (1.6L, 2004–2011)
• Citroën C4 I (LC), 1.6L, 2004–2011
• Other vehicles utilizing the 1755H6 exhaust system.

Always verify the specific fitment for your vehicle’s year and trim before installation.

Maintenance Tips

• Regular Inspection: Periodically check the buffer for signs of cracking, bulging, or excessive wear. Replace if any damage is observed.
• Clean After Exposure: If the vehicle operates in dusty or corrosive environments, clean the buffer and mounting surfaces to prevent buildup that could compromise sealing.
• Avoid Over‑Tightening: While securing bolts, ensure they are tightened to manufacturer specifications. Over‑tightening can damage the rubber, reducing its effectiveness.
