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 the 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 drones for deep throaty notes while still having a comfortable ride.
