Product Description

The HKS 31019-AT002 Hi-Power SPEC-L II Cat-Back Exhaust System is a high-quality performance upgrade for Toyota 86 and Subaru BRZ models equipped with the FA20 2.0L boxer-4 engine. Designed to replace the stock exhaust with a lightweight, straight-through system, it improves exhaust flow efficiency and enhances throttle response while delivering a sporty, engaging sound that remains comfortable for daily driving. Dual polished tips add visual appeal to the rear of the vehicle and complement the car's sporty character.

Constructed from durable stainless steel and engineered for direct bolt-on installation using OEM hangers and hardware, the Hi-Power SPEC-L II system balances improved performance with long-term reliability. The optimized muffler and piping layout help reduce back pressure and support more responsive mid-range power delivery. Whether used on a lightly modded 86/BRZ or part of a broader performance build, this exhaust system provides a distinctive sound and enhanced driving feel without excessive cabin drone.
