The Bosal 278-093 End Silencer is a high‑performance exhaust component designed to enhance the sound, efficiency, and overall driving experience of classic Mercedes-Benz models. This silencer delivers superior noise reduction while maintaining optimal exhaust flow, making it an essential upgrade for enthusiasts seeking both performance and compliance with modern emission standards.

Key Features

• Optimized Acoustic Design: The internal baffle system is engineered to absorb unwanted resonances, resulting in a smoother, more refined exhaust note.
• Robust Construction: Made from premium stainless steel, the silencer resists corrosion and high temperatures, ensuring long‑term durability.
• Seamless Fitment: Precision machining guarantees a perfect match with the original exhaust manifold, eliminating leaks and maintaining factory performance levels.
• Enhanced Flow Dynamics: The carefully calculated cross‑sectional area allows for unrestricted gas passage, improving horsepower and torque output.
• Compliance with Emission Standards: Designed to meet stringent European emission regulations without compromising on sound quality.

Compatibility

The Bosal 278-093 End Silencer is specifically engineered for the following Mercedes-Benz models, ensuring optimal fit and performance:

• W123 Series – Saloon (Coupe) – 4‑Cylinder Inline Engines
• W123 Series – 3‑Cylinder Inline Engines (Volvo‑style)
• Various engine power ratings ranging from 74 CV to 136 CV, including the 200 kW and 230 kW variants.

Its universal mounting hardware allows for straightforward installation on both left‑hand drive and right‑hand drive vehicles within this family.

Installation Overview

1. Remove Existing Silencer: Carefully detach the original exhaust terminal, ensuring all bolts and clamps are properly documented for reassembly.
2. Prepare the New Unit: Inspect the Bosal 278-093 for any manufacturing defects. Clean the mounting surfaces to guarantee a tight seal.
3. Mounting: Align the silencer with the exhaust manifold and secure it using the supplied bolts. Tighten to the manufacturer’s torque specifications.
4. Seal Integrity Check: Verify that all gaskets are seated correctly and that there is no leakage of exhaust gases.
5. Final Inspection: Re‑check all fasteners, perform a short test drive, and listen for any abnormal noises indicating improper installation.

Performance Benefits

Upgrading to the Bosal 278-093 End Silencer yields measurable improvements:

• Increased Power Output: Users report gains of up to 5 hp and 7 lb‑ft of torque, attributed to reduced backpressure.
• Improved Fuel Efficiency: A smoother exhaust flow translates into better combustion efficiency, lowering fuel consumption by approximately 2–3%.
• Enhanced Sound Profile: The silencer delivers a deeper, more resonant tone that is both pleasing to the ear and compliant with noise regulations.
• Reduced Exhaust Heat: Stainless steel construction dissipates heat more effectively, protecting surrounding components from thermal stress.

Maintenance Tips

While the Bosal 278-093 End Silencer is built for longevity, regular checks can extend its life:

• Inspect for rust or corrosion every 12,000 km.
• Ensure gaskets remain intact; replace if they show signs of wear.
• Clean the exterior surface periodically to prevent buildup of soot and grime.
• Avoid aggressive driving conditions that could cause excessive vibration, which may loosen mounting bolts over time.
