HKS Hi Power Exhaust for Lexus GS400

Each HKS exhaust system is vehicle specific- designed for only a particular engine/vehicle configuration. Using extensive computer-controlled flow analysis, dyno testing, and precision design fit, HKS produces maximum horsepower without dramatically depleting low-end torque. Each HKS exhaust system is flanged and comes with all gaskets and hardware to provide the easiest direct bolt-oninstallation possible. Additionally, they utilize factory mounting points and hanger locations and are emission and sound legal in all 50 states.
