The HKS Hi-Power Cat-Back Exhaust System is designed for the 2015+ Subaru WRX and WRX STI equipped with the FA20 and EJ25 turbocharged engines. Engineered to improve exhaust flow, deliver a sportier exhaust note, and provide the durability HKS is known for, it is an excellent upgrade for both street-driven and performance-oriented vehicles.

Optimized specifically for turbocharged boxer engines, the exhaust system improves engine breathing by increasing exhaust flow and reducing back pressure. This promotes improved throttle response, more efficient cylinder scavenging, and a broader, more usable powerband, helping the engine perform more efficiently across the rev range.

Manufactured from high-quality stainless steel, the system offers excellent corrosion resistance and long service life, even under demanding driving conditions. Its carefully engineered design delivers a deep, sporty exhaust note that enhances the driving experience while maintaining refined sound levels suitable for everyday use.

The HKS Hi-Power system is designed as a direct replacement for the factory exhaust and provides OEM-style fitment, making installation straightforward. It is also compatible with both factory and aftermarket components, making it an ideal choice for stock vehicles as well as more extensively modified Subaru builds.

In October 1973, two talented and young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not, or would not, produce. HKS pioneered the Japanese aftermarket industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back ECUs and sophisticated fuel management tools. HKS was clearly driving performance trends for Japanese vehicles forward!
