HKS Hi-Power Dual Exhaust System – Mitsubishi Evo X

Boosting the horsepower and torque of your Mitsubishi Evo X with a performance exhaust system comes with perks you can hear.

The HKS Hi-Power Dual Exhaust System is a cat-back system that installs easily and performs powerfully, ensuring that your engine can draw all the air it needs for high performance. The 2.9-inch piping is mandrel bent for better flow, and features stainless steel mufflers and a bung for the O2 sensor. Installation is a snap — it bolts to the existing stock exhaust hangers with no need for modifications.

While customers are telling us that they are feeling impressive power gains, they also tell us they LOVE the deep, low growling sound that this Lancer Evo X dual exhaust system makes. Moderately quiet at idle, it gives a nice roar during acceleration. Our staff of gearheads can tell you more about how this HKS Hi Power Exhaust system can enhance your Evo X.

Please Note: Direct bolt on, includes EVERYTHING for an easy installation. NO other modifications needed. Bolts up to the existing stock exhaust hangers.

Amazing but be Warned

Love this exhaust it sounds amazing and everyone knows that is me showing up. Not super loud but it is pretty loud and has a very aggressive sound. Be warned however the tips are a bit larger so u may have some trouble fitting an under tray without a lil work

HKS need i say more

This was the first thing i did on my 2015 GSR. like everyone been stating its sounds better then the stock 100%... now that i finally did over kill FULL BOLT ON's this once nice tamed exhaust is LOUD but not obnoxiously loud with pop pop pop stuff (im old school) pair this with with a Tubular manifold, downpipe and top it off with a test pipe... oh yeah with a gen2 3576R too lol... at start and Idle you can feel the heart of my slow car beating. When i got it tuned my tuner complimented me on the tone of my HKS. It wasnt super loud nor sound like a poochie cat lmao. The only draw back is the droning... with my setup but i still like it better then the obnoxious loud guys or gals....


sounds and looks really good on the car and you can feel the gains added to the power

Great exhaust

This is a great exhaust, the sound is perfect tone, the tips are massive and give the car a more aggressive look in the back. Worth the money.

Amazing sound and looks!

This exhaust is everything I dreamed of having on my Evo. When you get on the throtle it really opens up. I absolutely love this exhaust and would recommend it to anyone with and Evo.
