Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path. The large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power.
