The HKS Silent Hi-Power Cat-Back Exhaust System is designed for the Toyota Celica GT-Four ST185 equipped with the turbocharged 3S-GTE engine. It combines high-flow performance with a sporty yet refined exhaust note, making it the ideal upgrade for drivers seeking increased performance without sacrificing everyday driving comfort or long-distance usability.

The straight-through design, featuring 75 mm main piping, reduces back pressure and improves exhaust flow, allowing the engine to breathe more efficiently. This results in improved throttle response, more efficient cylinder scavenging, and a broader, more usable powerband while enabling the turbocharger to perform more efficiently throughout the rev range.

To reduce low-frequency cabin noise, the system incorporates HKS Silent Chamber Technology. The closed-end chamber minimizes unwanted resonance without restricting exhaust flow or reducing engine performance, providing a more comfortable driving experience during highway cruising while preserving the system's sporty exhaust character.

Manufactured entirely from SUS304 stainless steel, the exhaust system offers outstanding heat resistance, excellent corrosion resistance, and long-lasting durability. The redesigned muffler is packed with Advantex® glass wool, providing effective sound absorption while maintaining consistent performance over time. Selected components also feature hollow hanger hooks and pressed flanges to reduce overall system weight.

The system features a TYPE-H round muffler, a 120 mm polished exhaust tip, and is JASMA-certified, ensuring compliance with Japanese noise regulations. Designed as a direct replacement for the factory exhaust system, it provides OEM-style fitment for straightforward installation.

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!

Today, HKS is one of the world's most well-known brands and the obvious choice for you who builds a JDM car. In the assortment you will find everything from chassis products to exhaust systems and turbo kits. HKS is behind some of the coolest builds and professional drivers in the world, so when you choose HKS, you choose the best.
