The HKS Silent Hi-Power Cat-Back Exhaust System is designed for the Mitsubishi Lancer Evolution IV, V, and VI equipped with the legendary turbocharged 4G63T engine. It combines improved exhaust flow with refined acoustics, making it the ideal upgrade for drivers who want enhanced performance without sacrificing everyday driving comfort.

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. Optimized for turbocharged applications, the system is capable of supporting engine builds producing over 350 PS.

The Silent Hi-Power series utilizes the HKS Type-S muffler, which minimizes low-frequency cabin noise and unwanted resonance. During normal driving, the exhaust remains close to factory sound levels (91 dB stock versus 93 dB with the HKS system), while under acceleration it delivers a deep, sporty exhaust note that reflects the Evolution's motorsport heritage without becoming intrusive.

Manufactured from SUS304 stainless steel, the exhaust system offers outstanding heat resistance, excellent corrosion resistance, and long-lasting durability. It is finished with a 120 mm polished exhaust tip and is designed as a direct replacement for the factory exhaust system, providing OEM-style fitment for straightforward, bolt-on installation with no modifications required.

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.
