HKS Legamax Premium Rear Section Exhaust 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 are we 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. All HKS exhaust systems utilize a micro-fiber mesh sheet wrapping around the internals of the muffler tube to prevent muffler packing from escaping over time, thus increasing the durability of the system.
