The HKS Hi-Power specR exhaust tailored for GDB(E) chassis Subaru models with the EJ20 engine is a purpose-built performance exhaust. It refines exhaust flow and delivers a more assertive exhaust note compared with stock hardware, while matching the vehicle’s routing requirements. The specR is aimed at drivers seeking an OEM-matched upgrade with a sportier character.
