Constructed out of fully polished SUS304 Stainless Steel, the HKS Hi-Power exhaust system was designed for enthusiasts seeking a high quality performance exhaust system with increase in the exhausts tone depth. The RSX cat-back includes the rear muffler and mid/center pipe that bolts up to the OEM down-pipe.

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both forced induction and naturally aspirated applications. 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.

Intended for race and off-road applications, namely high power naturally aspirated or forced induction applications.
