Description
The HKS Hi-Power Exhaust provides an application-specific exhaust configuration. Application: 2002–2007 Subaru WRX / 2004–2007 Subaru WRX STI.
Design and operation
Pipe diameter, routing and silencer construction influence exhaust flow, sound and clearance. The useful comparison is the complete configuration: a rear-section assembly and a system that includes center piping do not replace the same factory components.
