Bosal 289-017 Middle Silencer

Introduction to the BOSAL 289‑017 Middle Silencer

The BOSAL 289‑017 Middle Silencer is a high‑performance exhaust component engineered for the Ford Transit Connect Mk1 Van and similar light commercial vehicles. Designed with precision machining and premium materials, this silencer delivers superior noise reduction while maintaining optimal engine breathing and fuel efficiency.

Key Design Features

Optimized Chamber Geometry

The internal chamber of the 289‑017 is meticulously shaped to create a controlled turbulence zone. This design enhances sound wave cancellation, resulting in a noticeable drop in exhaust noise without compromising backpressure.

High‑Grade Stainless Steel Construction

Constructed from 316 stainless steel, the silencer resists corrosion and high temperatures, ensuring longevity even under harsh operating conditions. The material also provides a lightweight yet robust structure that can withstand vibration and impact.

Precision‑Machined Baffles

Integrated baffles are engineered to disrupt sound waves efficiently while allowing exhaust gases to flow smoothly. This balance reduces acoustic energy and improves overall exhaust performance.

Seamless Integration with Existing Exhaust Systems

The silencer features a standard 1‑inch (25 mm) flange that matches the Ford Transit Connect Mk1 Van’s exhaust layout. Its compact dimensions allow for easy installation without requiring major modifications.

Performance Benefits

Noise Reduction

Users report a reduction of up to 15 dB in cabin noise levels, providing a quieter driving experience and improved passenger comfort.

Enhanced Fuel Efficiency

The optimized flow path reduces exhaust backpressure, which can lead to a modest increase in fuel economy—typically around 1–2 % for the Transit Connect Mk1 Van.

Improved Engine Response

By maintaining proper exhaust scavenging, the silencer helps preserve engine torque curves and throttle response, especially under high load conditions common in commercial use.

Installation Guide

Tools Required

• Socket set (1‑inch)
• Torque wrench
• Sealant or gasket material compatible with stainless steel
• Cleaning brush and solvent for exhaust surfaces

Step‑by‑Step Procedure

1. Safety First: Ensure the vehicle is parked on a level surface, the engine is cool, and all safety precautions are observed.
2. Remove Existing Silencer: Use the socket set to loosen and remove the bolts securing the current middle silencer. Carefully detach the unit, noting any gasket or sealant that may need replacement.
3. Clean Mounting Surfaces: Thoroughly clean the flange area on both the exhaust pipe and the new silencer with a solvent to remove rust, oil, and debris.
4. Apply Sealant: Place a fresh gasket or apply sealant as recommended by BOSAL to ensure a leak‑free fit.
5. Install New Silencer: Align the 289‑017 with the mounting flange, then secure it using the bolts. Tighten to the manufacturer’s specified torque setting (typically 45 Nm, but verify in the technical manual).
6. Check Alignment: Verify that the silencer is properly seated and that there are no gaps or misalignments.
7. Test Run: Start the engine, allow it to reach operating temperature, and listen for any abnormal noises. Confirm that exhaust gases flow smoothly through the new unit.

Maintenance Recommendations

• Periodic Inspection: Check for signs of corrosion or damage every 10,000 km (or as recommended by BOSAL).
• Clean Gaskets: Replace gaskets if they show wear to maintain a proper seal.
• Avoid Over‑Torqueing: Use the torque wrench to prevent bolt stripping and ensure longevity of the mounting hardware.

Compatibility Overview

The BOSAL 289‑017 Middle Silencer is specifically engineered for the Ford Transit Connect Mk1 Van’s exhaust architecture. Its dimensions, flange size, and internal geometry align with the vehicle’s mid‑exhaust section, ensuring a seamless fit without aftermarket adapters.
