MIA's Description

The HKS Legamax Premium Cat-Back Exhaust is an aftermarket exhaust system designed for the 2017+ Honda Civic Type-R (FK8). This system increases piping diameter from 3 inches at the main pipe to dual 2.4-inch pipes, leading to dual 3.8-inch burnt titanium tips.

The exhaust reduces back-pressure by 50%, allowing the turbine to spin more freely at low RPM and improving overall power and response. It is engineered to handle up to 532 HP without power loss and features a dual muffler and small resonator designed to eliminate drone while providing a deep, throaty sound for a comfortable ride. The system is made in Japan from SUS304 stainless steel and is the same weight as the OEM system.
