Description
The HKS Legamax Sports cat-back exhaust for the Honda Civic Type R FL5 uses a 75mm full straight-through design that reduces exhaust pressure by approximately 30% versus stock. A valveless layout keeps the sound clear and consistent, while a dedicated actuator that mimics the factory valve motor is included to prevent error codes after installation.
Features
- Centre pipe: 75mm straight-through, splitting to dual 60.5mm
- Tips: 119mm titanium with HKS logo engraving
- Exhaust pressure reduction: approximately 30% versus stock
- Valveless design with included dedicated actuator to replicate stock valve movement and prevent error codes
- SUS304 stainless steel construction
Fitment
- Honda Civic Type R, chassis FL5, engine K20C, 2022 onwards
Notes
- The dedicated actuator must be installed using the stock valve motor - this is included in the kit.
- Professional installation recommended.
- JDM product: any HKS certification applies to the Japanese market. Check your state's regulations before road use in Australia.
