The Mitsubishi Challenger is highly appreciated in the Australian 4WD community for its dependability, functionality, and off-road capabilities. Nonetheless, similar to numerous diesel SUVs, the Challenger isn't free from exhaust-related problems as time passes. An efficiently maintained exhaust system is crucial not just for peak engine performance but also for fuel efficiency, emissions regulation, and a more comfortable driving experience.

This blog will examine the typical problems encountered by Mitsubishi Challenger owners regarding the exhaust system, along with solutions or enhancements for improved long-term performance.
1. Excessive Smoke or Poor Fuel Economy

A clear indicator of an exhaust issue is the emission of excessive black smoke from the tailpipe. This frequently indicates that the vehicle is operating rich (excess fuel and insufficient air), which may be caused by a blocked or ineffective exhaust.

In numerous instances, the diesel particulate filter (DPF) or the catalytic converter might be obstructed. This may lead to higher back pressure in the exhaust system, causing reduced ...
... fuel efficiency and engine performance.

Solution: Cleaning or substituting the DPF or enhancing the complete exhaust system can address this problem. Transitioning to a high-flow exhaust decreases backpressure and enhances fuel efficiency.
2. Rust and Corrosion

Exhaust systems of the Mitsubishi Challenger, especially those made from mild steel, are prone to rust—particularly in regions with elevated moisture or salt exposure. With time, rust can corrode pipes and mufflers, causing leaks, noise, and decreased performance.

Repair: If the rust is slight, sanding and applying treatment to the surface could be beneficial. In general, it's advisable to substitute the corroded elements with 409 stainless steel parts, providing markedly improved corrosion resistance and extended longevity.
3. Rattling or Loud Noises

Noticing strange rattling or loud roaring sounds while driving may signal damaged or loose exhaust parts. This might be caused by a faulty muffler, a loose heat shield, or a broken pipe.

Repair: It is crucial to check the hangers, gaskets, and clamps for any signs of damage or wear. Swapping out these parts or upgrading to a more durable aftermarket exhaust system can remove these sounds and bring back quiet, effective functioning.
4. Loss of Power When Towing or Off-Roading

The Mitsubishi Challenger is commonly utilized for pulling trailers or exploring rugged terrain. Nonetheless, a blocked or limited exhaust system can hinder the engine's ability to “breathe” correctly, particularly when under significant loads.

Correction: Numerous drivers choose a performance exhaust enhancement that improves exhaust gas circulation. This not only recovers lost power but also enhances throttle response, particularly during climbing or towing.
5. Check Engine Light Related to Emissions

An O2 sensor or DPF sensor that is not working properly can activate the check engine light. Frequently, these problems are closely linked to obstructions or inefficiencies in the exhaust system.

Correction: Diagnostic scanning can identify the problem. Substituting the sensor or enhancing the exhaust to a more efficient design can avert future sensor malfunctions and expensive fixes.
