The BOSAL 177-673 End Silencer is a high‑performance exhaust component designed specifically for the Mitsubishi Colt VI series, including models equipped with 1.3 L, 1.1 L, LPG, and FlexFuel engines. This rear muffler delivers superior sound attenuation while maintaining optimal backpressure for enhanced engine efficiency.

Key Features

• Precision Engineering: Manufactured with a robust stainless‑steel construction that resists corrosion and high temperatures, ensuring long‑term durability under demanding operating conditions.
• Optimized Acoustic Design: The internal chamber geometry is engineered to reduce noise levels by up to 10 dB compared to stock exhaust systems, providing a quieter driving experience without compromising performance.
• Low Backpressure: Designed with an efficient flow path that minimizes resistance, allowing the engine to breathe freely and maintain peak horsepower output.
• Easy Installation: The silencer features standard mounting flanges compatible with Mitsubishi Colt VI exhaust manifolds. Quick‑fit adapters are included for seamless integration.
• Heat‑Resistant Coating: A high‑temperature protective layer safeguards the internal surfaces against heat damage, extending service life and preserving acoustic integrity.

Compatibility Overview

The BOSAL 177-673 End Silencer is engineered to fit a wide range of Mitsubishi Colt VI variants:

All these models share the same exhaust outlet dimensions, allowing the BOSAL 177-673 End Silencer to be a drop‑in replacement that preserves factory fitment while enhancing performance.

Installation Guide

1. Preparation: Disconnect the battery and ensure the vehicle is on a stable surface. Remove any existing exhaust components that may interfere with installation.
2. Mounting Flange Alignment: Position the silencer’s mounting flange against the rear exhaust manifold, aligning all bolt holes precisely.
3. Screw Securely: Tighten the mounting bolts to the manufacturer’s specified torque using a calibrated wrench. Avoid over‑tightening to prevent damage to threads.
4. Check for Clearance: Verify that the silencer does not interfere with suspension components or underbody panels. Adjust as necessary.
5. Final Inspection: Inspect all connections for leaks and ensure the exhaust system is sealed. Reconnect the battery and perform a short test drive to confirm proper operation.
