HKS Stainless Hiper Exhaust for Subaru Impreza GC8 EJ20
The HKS Silent Hi-Power Exhaust System is designed for selected two-door Subaru Impreza GC8 applications equipped with the turbocharged EJ20 engine.
It uses SUS304 stainless-steel construction and a Type-S oval silencer intended to provide a deeper sports exhaust note while helping control excessive noise and unwanted cabin resonance.
The system features a 75mm main pipe and a 120mm tailpipe, with vehicle-specific routing for the compatible GC8 exhaust layout.
