HKS Hi-Power SPEC-L II Cat-Back Exhaust System - Toyota GR86 / Subaru BRZ (2021+)
The HKS Hi-Power SPEC-L II Cat-Back Exhaust System is designed for the Toyota GR86 (ZN8) and Subaru BRZ (ZD8) equipped with the powerful FA24 boxer engine. Combining lightweight construction, improved exhaust flow, and refined acoustics, this system delivers a more engaging driving experience without compromising everyday comfort or practicality.
The exhaust system is manufactured from ultra-thin stainless steel, providing a significant weight reduction compared to the factory exhaust while delivering performance levels comparable to much more expensive titanium systems. The reduced weight contributes to improved throttle response, better weight distribution, and a more dynamic driving experience.
The optimized pipe diameter has been specifically engineered for the FA24 engine, improving exhaust flow and reducing back pressure. The result is quicker throttle response, more efficient power delivery, and a broader, more usable powerband throughout the RPM range.
The exhaust note has been carefully tuned to produce a deep, sporty sound with rich bass tones while effectively eliminating unwanted cabin drone and resonance. This makes the SPEC-L II an excellent choice for both everyday driving and spirited back-road performance.
The system is compatible with interchangeable exhaust tips available in titanium, carbon fibre, or blue stainless steel, allowing owners to customise the appearance of their vehicle to suit their personal style.
Designed as a direct bolt-on replacement, the system offers OEM-style fitment and complies with Japanese noise regulations, making it quieter than the HKS SPEC-L II 32016-BT004 variant.
