HKS Carbon-Ti Cat Back Exhaust - Subaru WRX/STI 2002-2007

Special Edition HKS Carbon / Titanium Hi-Power Exhaust systems are available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped stainless muffler shell, a 120mm titanium tip, and polished stainless steel piping.

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. For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies.
