Inspired and designed from endurance and GT racing in Japan, HKS developed its Mazdaspeed3 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. The HKS Exhaust design reduces restriction in the exhaust path, resulting in better exhaust flow and increased performance gains. HKS is an industry leader, only using high end materials to manufacture their product, result in HKS giving you a quality system for you ride.

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. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power systems are made from SUS304 stainless steel muffler and tip assemblies.

HKS system sounds and looks great and is a Speed Shop 3 must have upgrade.
