Hi-Power Single Exit Exhaust for the FR-S, BRZ, and GR86

The HKS Hi-Power Single Exit Exhaust for the 2013-2024 Scion FR-S, Subaru BRZ, and Toyota GR86 covers the full FA20 and FA24 production run with a single part number. The Hi-Power design delivers HKS's characteristic aggressive exhaust character in a single-exit tip configuration. More volume and definition than the Legamax series, with the Hi-Power's direct, open exhaust character that reflects HKS's motorsport background.

60.5mm Pipe, 93-94 dB(A), FA20 and FA24 Coverage

The BT002 covers both FA20 and FA24 applications with a single part number and consistent 60.5mm main pipe diameter, sized for the FA24's higher exhaust volume and appropriate for the FA20 as well. Sound level is approximately 93–94 dB(A) at 1m at WOT, consistent across both engine applications due to the muffler tuning being calibrated for the FA24's higher exhaust pulse energy. On the FA20, this produces a slightly more present sound than the SPEC-L2 at equivalent RPM.

Single Part Number Across the Full Platform Run

The Hi-Power Single Exit is for FT86, BRZ, and GR86 owners who want the aggressive HKS exhaust character in a single-exit layout. The single tip configuration is cleaner and more understated visually than the dual-exit options while delivering the same internal HKS tuning.

Calibrated for FA24, Works Well on FA20

The broad model year coverage from 2013 through 2024 makes this one of HKS's most flexible exhaust options for the platform. FA20 and FA24 engines, multiple chassis generations, one part number. Verify fitment for your specific application but the coverage is intentionally wide.

The FT Breakdown

The Hi-Power Single Exit is HKS's all-platform exhaust for the FT86 family. It is the direct, no-qualification choice for owners who want the HKS Hi-Power sound without needing to specify generation or exhaust layout. Good sound, broad fitment, HKS quality. Calibrating the BT002 for the FA24's higher exhaust pulse energy and then publishing it as covering both FA20 and FA24 is an unusual engineering decision — most manufacturers would either tune down to the FA20's level or release two separate part numbers. HKS chose to tune up to the FA24 and let the FA20 application benefit from that additional muffler volume capacity. The result is an FA20 installation that sounds slightly fuller than the SPEC-L2 at comparable RPM.
