HKS 23+ Civic Type R FL5 Legamax Sports Cat-Back Exhaust | 31021-AH005
Turbocharge Your Ride: Unleash -30% Exhaust Pressure with the HKS φ75 Full Straight Design and Φ119 Titanium Tail with HKS Logo
Rev Up the Thrill: Enjoy a crystal-clear sporty sound and cabin comfort with our innovative valveless design. The stock ECU manages output based on torque, so changing the exhaust alone keeps the output at stock levels. However, combining it with the Power Editor boosts performance from stock 250kw and 434.9 N.m to 252kw and 438.6 N.m. Further power enhancement is possible by increasing the boost with the Power Editor (model: 42018-AH013 for FL5).
Performance Boost:
- 30% lower exhaust pressure compared to stock.
- Increased exhaust efficiency with an enlarged pipe diameter and straight structure.
- Stock pipe diameter: φ60 → φ50×2 (valve closed), φ60×1 (valve open).
- LMS pipe diameter: φ74.7 → φ60.5×2.
Valveless Design Benefits:
- The stock exhaust has a valve mechanism, but our product is valveless.
- Avoid error codes with the included actuator, which replicates the stock valve mechanism.
- The stock motor's installation ensures no error codes, even after OBD inspections begin in Japan on October 1, 2024.
Experience the perfect blend of performance and reliability with HKS’s advanced exhaust system. Enjoy the thrill of increased power without the worry of error codes or inspection issues.
