Overview
Upgrade your 2022+ GR86/BRZ with the HKS Hi-Power SPEC-L2 cat-back exhaust system — a performance-focused bolt-on solution designed to enhance both sound and driving dynamics.
Constructed from ultra-thin S304 stainless steel, this exhaust system delivers significant weight reduction compared to the stock setup while maintaining excellent durability and corrosion resistance.
The SPEC-L2 design features equal-length dual outlets with large 94 mm diameter tips that not only improve rear-end aesthetics but also help produce HKS’ signature sporty, bass-rich exhaust tone with minimal unwanted drone thanks to an internal silent chamber.
Optimized for the FA24 engine, the system uses carefully selected pipe diameters (≈ 65 mm stepping out to dual 50.8 mm) that promote smoother exhaust flow and reduced back-pressure, contributing to improved throttle response and driving performance.
Weighing in at approximately 11.4 kg — substantially lighter than the OEM system — the SPEC-L2 helps reduce rear-end mass, aiding vehicle agility and handling.
Features
-
Ultra-thin S304 stainless steel construction for reduced weight and durability.

-
Engineered for sporty exhaust character with minimized drone.
-

Special Edition — HKS Hi-Power SPEC-L2 “THE BLUEST EDITION”
For enthusiasts who want performance with a distinctive visual statement, the Bluest Edition builds on the foundation of the standard SPEC-L2 with an eye-catching aesthetic twist and desirable exclusivity.
What Makes It Different
-
Features a striking blue gradient finish on the inner tailpipes, crafted with “ultimate blue” styling in mind — blending sporty aggression with refined visual appeal.

Maintains the same ultra-thin S304 construction and performance-oriented design as the regular SPEC-L2, including weight reduction and low back pressure.
-
Delivers the same deep, clean exhaust tone with minimized drone thanks to a straight-through silencer structure and silent chamber.
Compatibility
