2008-2015 Mitsubishi Evo X Hi-Power Single Exit Exhaust System by HKS

HKS Hi-Power Muffler came back with the same concept, "High Power & High Performance", and "Resonant Sound" and "Stylish" are harmonized together.

To maintain the exhaust efficiency, enlargement of the exhaust pipe is usually required; the sound level tends to be increased and low-tone. The exhaust system with a cannon ball-shaped shell usually has lower silencer capacity than an oval-shaped shell; therefore, to reduce the sound level, the pipe diameter is narrowed. However, a narrow pipe diameter also reduces the exhaust efficiency and increase the exhaust pressure. HKS utilized original unique technology to maintain the exhaust capacity and sound level to meet the JASMA standard which is more severe than the regular safety standard. Inner structure of the silencer was redesigned so the unwanted low exhausts resonance was eliminated, and the sound quality was improved.

Powerful rear view with the cannon ball-shaped & modern titanium color tips improve the appearance. Tuning cars race in circuits for a time attack have improved the appearance more stylish. To maintain large exhaust capacity, the pipe diameter of the exhaust pipe installed on the bottom of a vehicle must be enlarged, and the ground clearance must be narrow. HKS Hi-Power Muffler was designed to maintain sufficient ground clearance with redesigned flanges and layout.

Cedric Lopez
Amazing value for the price

Exhaust went above my expectations all the finishes were very nice and the removable silencer is my favorite feature. Install is straight forward and can be done alone. Sound and tone make me very happy even when the silencer is on. I would highly recommend this to any evox owner it’s a fair price for the single exit and I love that now I can choose if I wanna sound like a race car or cruise and actually relax without going deaf.

Sounds great!

Look and sounds great! The tip cover(burnt style) and polish tip is a smart move!

Great exhaust

This exhaust has the exact tone i was looking for. The noise level is great as well. Just loud enough to enjoy but not loud enough to piss off the neighborhood.

Love the exhaust!

This exhaust was everything I hoped for. Great sound. It is quiet at idle but when you get on it is loud and has a good note. Would recommend to anyone looking for an exhaust system for an Evo!
