The HKS Legamax Premium Cat-back Exhaust for the new 2017+ Civic Type R is the very first in their complete product lineup!

This exhaust increases piping diameter in each stage, making it a 3-inch main pipe to dual 2.4-inch pipes into the mufflers and finally out of dual 3.8-inch Burnt Titanium Tips. Overall the exhaust reduces back-pressure by 50%, this allows the turbine to spin more freely from a low RPM and improves overall power and response across the power-band.

This exhaust system has been engineered and designed to handle up to 540 ps (532 HP) without any power loss, so it's great for high power builds. It also features a dual muffler and small resonator that is guaranteed to provide zero drone for deep throaty note while still having a comfortable ride.

    HKS Legamax for FK8

    I had this exhaust before and sold it...missed it after trying greddy and Tomei. Now I have it again and won't ever get rid of it. I'm running catless downpipe and front pipe and have no drone. I get some of the rumble crackle sound also. Love this exhaust!

    Great build and value love the sound

    Every bit as good of build quality as HKS has been known for. Sound of it was deep and no drone in cab. A little heavier than some other exhausts but rather hear my exhaust note outside than inside.
