HKS Hi-Power Exhaust systems incorporate a race inspired angled mounted stainless steel muffler and piping design for greater flow and higher-PRM power gains. Fits Subaru WRX/STi 02+
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged 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. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
