Bosal 185-479 End Silencer – The Ultimate Rear Muffler Solution

The BOSAL 185‑479 End Silencer is a high‑performance exhaust component engineered to deliver superior sound attenuation, durability, and compatibility with a wide range of Opel and Vauxhall models. Designed as a rear muffler (end silencer), it seamlessly integrates into the existing exhaust system while providing noticeable improvements in noise reduction and overall exhaust flow.

Key Features & Technical Specifications

• Model Compatibility: Specifically crafted for the Opel Zafira A (T98) MPV/Space Wagon, including both petrol and LPG variants. It also fits Vauxhall Zafira MK I models with engine outputs ranging from 74 kW to 92 kW.
• Material Construction: Made from high‑grade stainless steel or heat‑resistant alloy steel, ensuring resistance to corrosion, heat, and mechanical stress over extended periods.
• Design Architecture: Features a multi‑stage chamber layout that optimizes exhaust backpressure while maintaining efficient gas flow. The internal baffles are engineered to disrupt sound waves, providing effective noise suppression without compromising performance.
• Dimensions & Fitment: Tailored to match the exact mounting points and flange specifications of the target vehicles, guaranteeing a snug fit that eliminates leaks and vibration.
• Weight: Lightweight construction reduces overall vehicle weight, contributing to better fuel economy and handling dynamics.

Performance Benefits

The BOSAL 185‑479 End Silencer delivers multiple advantages for drivers seeking a balance between quiet operation and robust exhaust performance:

• Significant Noise Reduction: The advanced baffling system cuts noise levels by up to 30 dB, ensuring a quieter cabin experience.
• Improved Exhaust Flow: By minimizing backpressure, the silencer allows exhaust gases to exit more freely, which can enhance engine breathing and potentially increase horsepower marginally.
• Enhanced Durability: The use of corrosion‑resistant materials protects against rust and oxidation, extending the component’s lifespan even in harsh climates.
• Reduced Vibration: Precision machining and balanced internal geometry dampen vibrations that could otherwise transmit to the vehicle chassis.

Installation Overview

Installing the BOSAL 185‑479 End Silencer is a straightforward process for experienced mechanics or knowledgeable DIY enthusiasts. The following steps outline the typical installation procedure:

1. Preparation: Safely lift the vehicle and secure it on jack stands. Remove any existing rear muffler or exhaust components that may obstruct access.
2. Removal of Old Muffler: Disconnect the exhaust pipe fittings, carefully detach the old silencer, and set aside for recycling if desired.
3. Mounting the New Silencer: Align the BOSAL 185‑479 with the mounting brackets. Use high‑temperature exhaust bolts to secure it firmly in place.
4. Sealing & Gasket Replacement: Install new gaskets or sealing rings to ensure a leak‑free connection between the silencer and the exhaust pipe.
5. Reassembly: Reconnect any remaining exhaust components, double‑check torque specifications, and perform a quick visual inspection for alignment.
6. Testing: Start the engine and listen for proper operation. Verify that there are no abnormal noises or vibrations indicating a misfit.

Compatibility Summary

The BOSAL 185‑479 End Silencer is specifically engineered for the following vehicle models and configurations:

• Opel Zafira A (T98) MPV/Space Wagon – Petrol engines ranging from 1.6 L (74 kW) to 1.8 L (92 kW), including dual‑fuel LPG variants.
• Vauxhall Zafira MK I (A) – Similar engine outputs and body styles as the Opel counterpart, ensuring cross‑compatibility.

Its design adheres to OEM specifications for flange size, bolt pattern, and exhaust pipe diameter, guaranteeing a seamless fit without the need for extensive modifications.
