Product Details

HKS is well-known for making performance parts that are built to last and offer an improved driving experience. This SILENT Hi-Power cat-back exhaust system is designed for the GC8 chassis with the EJ20 Turbo engine, offering a refined exhaust note without being overly loud. It's a popular choice for Subaru enthusiasts looking to enhance their vehicle's sound and performance.

This cat-back system replaces the factory muffler and piping from the catalytic converter back. It's constructed from SUS304 stainless steel, which is strong and resists corrosion, ensuring it holds up well over time. The design focuses on reducing drone at cruising speeds while still providing a satisfying, deeper tone when you accelerate. The piping diameter is optimized for the EJ20 Turbo engine to help improve exhaust flow, which can lead to a slight increase in throttle response and overall power. Installation is typically a bolt-on affair, replacing the stock exhaust components.

When installing this system, you'll want to ensure all hangers and connections are properly secured. The goal of the SILENT Hi-Power series is to offer a noticeable improvement in sound and performance while maintaining a comfortable level of noise inside the cabin, making it suitable for daily driving. This exhaust is a solid option for anyone wanting to upgrade their GC8's exhaust system with a well-made, performance-oriented part from a reputable brand.
