The HKS Hi-Power Cat-Back Exhaust System is designed for the Nissan Skyline GT-R R32 equipped with the legendary RB26DETT engine. It combines high exhaust flow, a sporty exhaust note, and long-lasting durability in a system engineered specifically for turbocharged engines, making it an excellent upgrade for both high-performance street cars and track-focused builds.

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 stainless steel, offering excellent heat resistance and superior sound absorption while keeping manufacturing costs lower without compromising quality or performance.

The straight-through muffler design, combined with an optimized pipe layout, reduces back pressure and improves exhaust flow, allowing the engine to breathe more efficiently. The result is improved throttle response and a deep, sporty exhaust note with refined sound levels suitable for both everyday driving and spirited performance use.

Inside the muffler, HKS uses Advantex® glass wool, a continuous high-temperature fiberglass material that provides excellent sound absorption while maintaining its performance under prolonged high-temperature operation. The exhaust system is also JASMA-certified, ensuring compliance with Japanese noise regulations for street use.

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!
