HKS Hi-Power SPEC-L Cat-Back Exhaust System - Toyota GR86 ZN8 / Subaru BRZ ZD8 FA24 (2021+)
The HKS Hi-Power SPEC-L is a lightweight cat-back exhaust system developed for the Toyota GR86 ZN8 and Subaru BRZ ZD8 (2021+) equipped with the naturally aspirated 2.4-litre FA24 boxer engine. Engineered to provide improved airflow and reduced back pressure, the system helps deliver improved engine performance, quicker throttle response, and enhanced power delivery. At the same time, it produces a deep exhaust note under acceleration while minimising unwanted cabin resonance during everyday driving.
To reduce weight, HKS uses thin-wall piping and silencers manufactured from SUS304 stainless steel, providing outstanding corrosion resistance, excellent heat resistance, and long-lasting durability. The vehicle-specific pipe routing and optimised pipe diameter promote efficient exhaust flow while ensuring OEM-style fitment, and the large-diameter titanium tailpipe gives the rear of the vehicle a distinctive, motorsport-inspired appearance.
Designed for direct bolt-on installation, the HKS Hi-Power SPEC-L uses vehicle-specific mounting points for straightforward installation without requiring modifications. The exhaust system is also available in two sound levels depending on the part number, allowing enthusiasts to choose a specification that suits both daily driving and performance-focused applications for street and track use.
