Achieve low exhaust pressure, while increasing power and exhaust performance.  This will provide a more aggressive exhaust tone while not been excessively loud.  

• Full Straight Pipe achieves Low Exhaust Pressure!The D75mm pipe and full straight structure with no restrictions achieves 30% lower exhaust pressure compared to stock. D119mm Titanium tail with HKS logo is makes a sporty rear view.
• Highly Emotional and Aggressive Sound!By adopting a bullet-shaped silencer for the main silencer and valveless structure, you can enjoy a pleasant exhaust sound that emphasizes not only the bass note but also the treble note. The sound pressure is increased throughout the entire frequency range, resulting in a more powerful sound than the existing LEGAMAX Sports.

APPLICATION

• HONDA CIVIC TYPE R FL5 (2023, 2024, 2025+)

FEATURES

• Power output is above stock from 5000 to 6000 rpm, with a maximum increase of 3.6Kw.
• Torque increases up to 7.5 Nm around 3000 rpm and exceeds the stock from 5000 rpm to 6000 rpm.
• Exhaust pressure is reduced by about 30% compared to the stock exhaust pressure and exhaust efficiency is improved, so further power increase can be expected by rewriting the ECU.*
• Exhaust sound level is increased by 13dB compared to the stock. 9dB increase compared to existing HKS LEGAMAX Sports.
• In terms of sound quality, not only the bass range but also the treble range has increased significantly compared to the stock system, and compared to the LEGAMAX Sports, the frequency waveform is similar, but the overall sound pressure has increased, resulting in a more powerful exhaust sound.
• The more you step on the gas pedal, the more you can enjoy the elated exhaust sound.
• Although the stock muffler has a valve mechanism, this product is valveless.
• By using the supplied actuator, error codes that may occur due to the valveless design can be avoided.
• Included actuator replicates the mechanism of the stock valve. By attaching the stock motor, the actuator moves in the same operation as the stock valve, thus eliminating error codes.
• FL5 will record an error code if the stock motor idle or is removed. *Check lamp will not be illuminated.
• By connecting a diagnostic equipment to OBD, it is possible to check for the presence of error codes.
• Exhaust valve actuator included

*Since the stock ECU manages engine output based on torque output, so if the exhaust is replaced without ECU remapping, maximum output will be the same as the stock.
