HKS SILENT Hi-Power for GDB/GDA/GGA EJ20 Turbo is a quieter Hi-Power muffler solution made for those GDB, GDA, and GGA chassis equipped with EJ20 turbo engines. It offers reduced exhaust harshness relative to standard Hi-Power units while remaining explicitly matched to these Subaru model variants and their turbocharged EJ20 configurations.
