Legamax Premium Cat-Back Exhaust for 17+ Civic Type-R by HKS

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.

Customer Reviews

Based on 4 reviews
A bit louder than stock, sounds great

Easy install and great fitment. Right after install, it was a little bit drone-y around 2500-3000 rpm on the highway, but after 1000 miles it has either broken in or I've gotten used to it. Not terribly loud but the sound itself is deep and throat-y, as much as an FK8 can sound that way.

Joaquin Miguel Ranjo
Perfect Exhaust for FK8

Fast shipping and legit customer service. Easy to install, took us about an hour to finish.
Good quality and Sounds great! I have a new 7 month old baby and he can still easily fall asleep as it's not too loud.
Thanks Liken Motorsports!

Dane Panos
Perfect with the right down pipe

This exhaust paired with my RV6 catless downpipe has really woken up the car. It's loud when you want it and calms when cruising. Liken as always with great shipping as well.

Best exhaust ever!!!
