The HKS Silent Hi-Power Cat-Back Exhaust System is designed for the Toyota Celica GT-Four ST205 equipped with the turbocharged 3S-GTE engine. It offers the ideal combination of enhanced performance, refined acoustics, and excellent everyday driving comfort. Developed for enthusiasts who want to improve engine performance while maintaining a comfortable sound level, it is equally suited to daily driving and spirited performance use.

The straight-through design, featuring 75 mm main piping, reduces back pressure and optimizes exhaust flow, allowing the engine to breathe more efficiently. This results in improved throttle response, more efficient cylinder scavenging, increased engine output, and a broader, more usable powerband throughout the entire RPM range.

The system incorporates HKS Silent Chamber Technology, which minimizes low-frequency cabin noise and unwanted resonance without compromising performance. The result is a deep, sporty exhaust note that enhances the driving experience while remaining comfortable during highway cruising and long-distance journeys.

Manufactured entirely from SUS304 stainless steel, the exhaust system provides outstanding corrosion resistance, excellent heat resistance, and long-lasting durability. The TYPE-H round muffler, combined with a 120 mm polished exhaust tip, delivers the signature HKS appearance while ensuring efficient exhaust flow.

The system is JASMA-certified, ensuring compliance with Japanese noise regulations, and is designed as a direct bolt-on replacement for the factory exhaust system. Installation requires no modifications and retains the vehicle's original exhaust routing.

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!
