HKS Silent Hi-Power Exhaust for Subaru Impreza GDB EJ20
The HKS Silent Hi-Power Exhaust is a vehicle-specific performance exhaust system designed for compatible Subaru Impreza GDB models equipped with the EJ20 turbocharged engine.
It combines a straight-through exhaust layout with HKS sound-control technology, helping improve exhaust flow while maintaining a refined sound level suitable for road-focused performance use.
The system is manufactured from SUS304 stainless steel for durability, corrosion resistance and a polished finish. Its Silent Chamber design helps reduce intrusive low-frequency noise inside the cabin.
