The HKS Hi-Power Cat-Back Exhaust System is designed for the Nissan Skyline R34 GTT (ER34 2-door) equipped with the RB25DET engine, offering an ideal balance of improved exhaust flow, a sporty exhaust note, and everyday driving comfort. Engineered to improve engine breathing while maintaining refined sound levels, it is an excellent upgrade for both street-driven and performance-oriented vehicles.

The rear muffler and exhaust tip are manufactured from SUS304 stainless steel, providing outstanding corrosion resistance, long service life, and a premium polished finish. The concealed exhaust piping is constructed from SUH409 coated steel, offering excellent heat resistance and superior sound absorption while maintaining durability without restricting exhaust flow.

The straight-through muffler design reduces back pressure and improves exhaust flow, promoting more efficient cylinder scavenging, improved throttle response, and a broader, more usable powerband. The result is the deep, sporty exhaust note that defines the HKS Hi-Power series while maintaining comfortable sound levels during everyday driving.

The exhaust system is also JASMA-certified, ensuring compliance with Japanese noise regulations while delivering an excellent balance of performance, sound quality, and durability.

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!
