The HKS LEGAMAX Premium catback exhaust is specified for the Subaru Impreza GRB with the EJ20 turbo engine. Offered as a vehicle‑specific catback system, it replaces the factory exhaust section for that application and is intended to be fitted to the GRB chassis and EJ20 turbo engine combination where a direct‑fit aftermarket catback is required.
