HKS has developed the perfect cat back exhaust system for those of you who don’t exactly want an aggressive tone, but can appreciate improvements in exhaust performance and style. This is the HKS Silent Hi-Power exhaust system that has been designed with implemented resonators to hinder aggressive sound tones that are inherent with most aftermarket exhaust systems. The HKS Silent Hi-Power Exhaust comes with everything needed to be ready for installation. This includes both hardware, as well as gaskets. The exhaust hangers have been welded in an OEM location on the mufflers and piping. Additionally this exhaust system has been fabricated from 304 stainless steel to be weather resistant, and to provide users with years of performance.
