Best Exhaust Guide for Mitsubishi Delica (1995–1999)
If you own a Mitsubishi Delica you already know it's not your average 4x4. It's a cult classic part people mover, part off-road weapon and entirely underrated. Whether you're running it as a daily driver, a weekend tourer or a full blown overland rig one of the best upgrades you can make is a quality exhaust system.
A proper Outback Exhausts system doesn't just make your Delica sound better it frees up power, improves turbo response, reduces EGTs and can even help fuel economy on long hauls. In this guide we'll walk you through everything you need to know about choosing the right exhaust for your Delica and show you exactly what we offer here at Outback Exhausts.
Why Upgrade Your Mitsubishi Delica Exhaust?
The factory exhaust on the Delica was designed with cost and noise suppression in mind not performance. The 4M40 turbo diesel is a tough, torquey engine but it's being held back by a restrictive stock exhaust. Here's what a quality upgrade actually does for you:
- More power and torque — reducing backpressure lets the turbo spool faster and breathe more freely
- Lower exhaust gas temperatures (EGTs) — critical if you're towing or running hard in the heat
- Better fuel economy — a more efficient exhaust means the engine doesn't have to work as hard
- A proper exhaust note — not obnoxiously loud, just purposeful and satisfying
- Longevity — premium stainless steel outlasts the factory mild steel by years

SWB vs LWB — Does It Actually Matter for the Exhaust?
Yes, it does. The SWB and LWB Delica have different chassis lengths, which means the exhaust routing and pipe lengths differ. Running the wrong system can result in fitment issues, rattles or clearance problems. Always confirm your wheelbase before ordering if you're unsure, check your compliance plate or give us a call and we'll sort it out for you.
Resonator + Muffler vs Straight Pipe — Which Should You Choose?
This comes down to how you use your Delica and how much sound you can live with day to day.
The Resonator + Small Muffler option gives you a medium exhaust note noticeably better than stock with a deep diesel rumble that's satisfying without being antisocial. It's the pick for daily drivers, family tourers and anyone who spends time on highways or in suburban areas.
The Straight Pipe option removes the muffler entirely for maximum flow and a loud aggressive note. It's the choice for dedicated off road rigs, track days or builds where outright performance matters more than cabin comfort. Just be aware it will be louder inside the cabin too especially on long drives.
