The HKS Legamax Premium Cat-Back Exhaust System is designed for the Honda Civic FK7 Hatchback, offering the perfect combination of enhanced performance, refined acoustics, and premium styling. Engineered to deliver a sportier exhaust note while maintaining excellent everyday driving comfort, it is an ideal upgrade for both daily-driven and enthusiast vehicles.

The straight-through design reduces back pressure by up to 50% compared to the factory exhaust system, improving exhaust flow and allowing the engine to breathe more efficiently. This results in quicker throttle response, more efficient cylinder scavenging, and a broader, more usable powerband without excessive exhaust noise.

Manufactured from high-quality stainless steel, the exhaust system provides outstanding corrosion resistance, excellent heat resistance, and long-lasting durability. The signature blue-gradient titanium exhaust tips, featuring the HKS logo, give the vehicle a premium motorsport-inspired appearance.

The exhaust note has been carefully tuned to produce a deep, sporty tone under acceleration while keeping cabin drone and unwanted resonance to a minimum during everyday driving. The system is also JASMA-certified, ensuring compliance with Japanese noise regulations.

Designed as a direct replacement for the factory exhaust system, the Legamax Premium offers OEM-style fitment for straightforward bolt-on installation with no modifications required.
