The HKS Hi-Power 409 is a cat-back exhaust system built for Nissan Silvia PS13 and RPS13 models with SR20DET engines from 1989 to 1994. It replaces the stock system from the catalytic converter back with mandrel-bent piping and a large-volume silencer for improved exhaust flow power gains and a deep aggressive sound. Weighing just 12kg this stainless steel setup reduces weight while enhancing throttle response and mid-range torque.
