Description
The HKS LEGAMAX Premium Exhaust provides an application-specific exhaust configuration. Application: Subaru WRX (VBH). Only the identified rear section is represented by this configuration.
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.
