The HKS metal catalyzer is a direct-fit catalytic component for GRB chassis applications when used with the matching front pipe. Built to follow the original exhaust routing, this HKS unit replaces the factory catalytic section without requiring major modifications. It’s intended for owners who need a vehicle-specific catalyzer that integrates with existing exhaust hardware.
