03-06 Evolution 8 & 9 HKS Hi-Power Catback

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for the 2003-2006 Lancer Evolution 8 & 9 to produce looks and performance. HKS has incorporated their race inspired, offset muffler and piping design into the Evolution 8/9 Hi-Power. This offers greater flow and higher-RPM power gains due to the less restrictive design. The Evolution High-Power HKS exhaust's large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. The Evolution 8 & 9 Hi-Power exhaust systems consist of 75mm diameter piping, muffler and 120mm tip assemblies. HKS offers a less expensive mild-steel version and a more expensive, more durable stainless steel cat back.
