The HKS Legamax Exhaust System is the perfect exhaust system for those looking for a quality exhaust system designed to improve throttle response, and add both horsepower, and torque. The Legamax exhaust system also has a mature tone. You get the aggressive tone that 75MM piping will provide, however HKS has designed a 101.6MM silencer, as well as a silent chamber in the exhaust system for those of you who want the performance without attracting extra attention.

This is a direct bolt-on component that has exhaust hangers welded onto the OEM locations for great fitment without the need for modification. Hardware and gaskets will be provided to make for a ready installation.
