HKS Legamax Premium Exhaust Center Pipe Subaru WRX STI 08+

Increasing the amount of exhaust flow is the first progressive step to increased engine performance and efficiency. The factory exhaust system represents a restriction in the stock configuration. By designing a system that increases the mass and velocity of exhaust flow, it allows for a reduction in backpressure and thermal stress, thus unleashing the engines potential for increased power, torque and responsiveness.

All HKS exhaust systems are engineered with performance, quality, and value as primary goals. Through countless comprehensive efforts of flow analysis, dyno testing and tuning HKS is able to maximize horsepower gains throughout a broad powerband, while maintaining reasonable sound levels for street use. HKS Exhaust Systems that are designated for street use retain all factory emissions equipment and conform to the California Vehicle Code 95-decibel exhaust noise level limit.

HKS exhausts systems are designed for direct bolt on fitment to the stock flanges and come with all the necessary gaskets and hardware to provide simple installation and long term durability.

  • Center Pipe Only
  • For use with 31021-AF012 or Stock Muffler
  • 65mm Piping
