The HKS Super Turbo muffler cat-back exhaust is specified for 2014+ Subaru WRX STI (EJ20) applications as a direct-replacement muffler system. It replaces the stock rear muffler section to alter exhaust flow and tone while retaining a bolt-on catback layout. This HKS unit is intended for owners seeking a factory-location catback swap that modifies the vehicle's exhaust character without extensive fabrication.
