Passionately crafted and inspired by the endurance and GT racing scene in Japan, HKS has developed their Hi-Power Exhaust system for both turbocharged and naturally aspirated vehicles. This new design incorporates a race-inspired offset muffler and piping, resulting in a smoother and less restrictive exhaust flow. With fewer bends and a straighter path, high-PRM power gains are achieved. Turbocharged engines experience improved mid-range boost response and high-RPM power, while naturally aspirated vehicles benefit from increased exhaust flow capacity as engine tuning is pushed to the limit. Some models are even available in a Silent Hi-Power version with an inner silencer built into the muffler. Utilizing SUS304 stainless steel, the Hi-Power Exhaust provides similar performance enhancements as the renowned Drager Exhaust systems. Upgrade your vehicle's performance by eliminating the restrictions of the OEM exhaust design with HKS's premium exhaust system.
