HKS Legamax Premium Cat-back – Honda Civic Type R FK8

The HKS Legamax Premium Cat-back Exhaust is the first in HKS’s full lineup for the 2017+ Honda Civic Type R (FK8), engineered to deliver both power and comfort. Featuring a 3-inch main pipe that transitions into dual 2.4-inch pipes, this system flows into twin mufflers and exits through dual 3.8-inch burnt titanium tips. The design reduces back pressure by up to 50%, allowing the turbo to spool more freely from low RPM, improving response and delivering stronger power across the rev range.

Built to handle up to 540 ps (532 hp) without loss, this system is ideal for both stock and high-power builds. Despite its performance gains, the Legamax Premium maintains the same weight as the OEM exhaust, ensuring balance and reliability. A dual muffler with a small resonator eliminates drone, giving the Civic Type R a deep, throaty tone while keeping daily driving comfort intact.
