HKS Silent Hi-Power Cat-Back Exhaust System - Mitsubishi Lancer Evolution IX / Wagon 4G63 (2005-2007)
The HKS Silent Hi-Power Cat-Back Exhaust System is designed for the Mitsubishi Lancer Evolution IX and Evolution IX Wagon equipped with the turbocharged 4G63 engine. It combines high-flow performance with refined acoustics, offering the ideal balance of power, comfort, and durability for both daily-driven vehicles and performance-oriented builds.
The straight-through design 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.
The system incorporates HKS Silent Chamber Technology, which minimizes low-frequency cabin noise and unwanted resonance without restricting exhaust flow or performance. Combined with the straight-through muffler design and sound-absorbing Advantex® glass wool, it delivers a deep, sporty exhaust note while effectively reducing high-frequency noise and unwanted cabin drone.
Manufactured entirely from SUS304 stainless steel, the exhaust system offers outstanding heat resistance, excellent corrosion resistance, and long-lasting durability. Its lightweight construction features hollow hanger hooks and pressed flanges to reduce overall weight without compromising strength. The system is also JASMA-certified and designed as a direct replacement for the factory exhaust system, providing OEM-style fitment for straightforward installation.
