Mitsubishi Mirage Exhaust System: The Part That Announces Its Own Problems
On the Mitsubishi Mirage, sound is usually the first clue here, ahead of any visual sign — a rattle, a drone, noise that's crept in gradually or arrived overnight. It's one of the more forgiving faults in that sense, since your ears will likely flag it before it becomes a bigger problem.
Mitsubishi Mirage Exhaust System: What It Does
The Mitsubishi Mirage's exhaust system handles three things at once: clearing burnt gases from the engine, cutting noise via the silencer, and treating emissions through a catalytic converter and particulate filter. Because petrol and diesel emissions requirements differ, it often uses genuinely different exhaust systems depending on engine type.

A Genuinely Useful Piece of Context Worth Knowing About Mitsubishi's DPF History — Mitsubishi Mirage Exhaust System
If you're cross-shopping against a diesel Outlander or L200, this is genuinely worth knowing: documented cases describe DPF faults returning shortly after replacement, in at least one case traced to technicians accidentally damaging the turbo boost pipe during the original repair work, rather than the replacement part itself being faulty. This doesn't directly affect this specific model, but is worth knowing as context if you ever face a similar recurring DPF issue.
It's also worth knowing that an EGR valve sticking open can cause excessive soot accumulation that then gets misdiagnosed as a DPF fault specifically, and that a low or empty DPF additive fluid level can trigger warning lights that look identical to a genuine filter fault.
