Description
The HKS Hi-Power SPEC-L II Exhaust provides an application-specific exhaust configuration. Application: Subaru Impreza WRX STI (GRB/GRF).
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.
