HKS Hi-Power Cat Back Exhaust System
The HKS Hi-Power Cat Back Exhaust System is built for enthusiasts who demand performance and an unmistakable exhaust note. With a large 75mm main pipe and a valveless layout, this system reduces exhaust pressure by approximately 30% compared to the factory setup—resulting in improved flow, quicker throttle response, and better tuning potential.
At the rear, a bold 119mm titanium tailpipe adorned with the HKS logo delivers a striking, motorsport-inspired finish. The bullet-style silencer, also valveless, produces an aggressive and emotional exhaust note, offering deeper bass and sharper high-end tones—more dynamic and exhilarating than the LEGAMAX Sports system.
In terms of performance, the Hi-Power system delivers gains where it matters most:
Power increase of up to 3.6kW from 5000–6000 rpm
Torque improved by up to 7.5 Nm around 3000 rpm, maintaining gains through 5000–6000 rpm
Lower backpressure enhances efficiency and supports further upgrades with ECU tuning
Perfect for drivers seeking both form and function, this is an exhaust that sounds as serious as it performs.
