Bosal 255-088 Rubber Buffer – The Ultimate Exhaust Silencer
The Bosal 255-088 Rubber Buffer is a high‑performance component designed to enhance the exhaust system of Volkswagen commercial vehicles such as the Transporter, IV, Bus, Caravelle, T4, and Multivan. This rubber strip functions as an effective silencer, reducing noise levels while maintaining optimal exhaust flow.
Key Features & Benefits
- Superior Noise Reduction: The engineered rubber material absorbs vibration and dampens sound waves, delivering a quieter driving experience.
- Durable Construction: Made from premium elastomer blends that resist heat, corrosion, and mechanical wear, ensuring long‑term reliability.
- Easy Installation: The buffer is designed to fit seamlessly onto the existing exhaust mounting brackets of VW models, requiring minimal modification.
- Enhanced Exhaust Flow: Unlike traditional mufflers that restrict airflow, this rubber strip allows gases to pass freely while still providing sound attenuation.
- OEM Compatibility: Identical in performance and design to the original equipment, guaranteeing a perfect fit for both new and replacement applications.

Installation Guide
- Preparation: Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect any existing exhaust components that may interfere with installation.

- Securing: Use the provided fasteners or compatible bolts to secure the buffer in place. Tighten evenly to prevent uneven stress on the rubber material.
