Upgrading your Evo’s factory exhaust system comes with a slew of benefits regardless of whether you’re daily driving or attending regular track days.
If you’re missing an aggressive tone on your Mitsubishi Evo X and find yourself scrolling through aftermarket exhaust systems occasionally, we got you covered.
In this guide, we’ll explore some of the best exhausts for your Evo X along with in-depth reviews of each upgrade.
How Good Is the OEM Mitsubishi Evo X Exhaust System?
Overall, the OEM Mitsubishi Evo X exhaust system isn’t bad, but it will, be a restrictive barrier to true sports car enthusiasts looking to modify their Evo X.
The factory exhaust system is equipped with a 2.5” pipe with restrictive canisters. Upgrading it with a straighter 3.0” full cat-back system will give you a refined tone and more power.
What Are the Benefits of Upgrading?
There is no doubt that upgrading your stock exhaust to a premium system will improve the performance of your Evo X.
Some of the most noticeable differences include:
- Better Sound: If you thrive on an extremely loud sound with deep rumbles and aggressive tones, a performance exhaust system will meet your expectations. You won’t be disappointed by the extra attention while driving your Evo X down the street.
- Improved Performance: A high-performance exhaust system has a less restrictive design that allows for better gas flow, resulting in power gains.
- Increased MPG: The freer the exhaust, the faster the accumulated gas can run out, which improves engine performance — leading to better fuel economy.
- Less Weight: Most aftermarket upgrades use lightweight construction to reduce weight as much as possible — less weight means better acceleration and handling.
