Product Details

If you're looking to refine the sound and performance of your GH-GDB(E) EJ20, the HKS SILENT Hi-Power cat-back exhaust system is a solid choice. This system is designed to replace the factory exhaust from the catalytic converter back, offering a more refined tone and potentially improved exhaust flow compared to the stock setup. HKS has a long history of producing well-regarded exhaust components, and this cat-back aims to balance a sportier sound with everyday drivability.

Constructed from SUS304 stainless steel, this exhaust is built to resist corrosion and maintain its appearance over time. The large-diameter piping and the specially designed muffler work together to reduce drone at cruising speeds, which is a common concern with aftermarket exhausts. This means you get a more noticeable, pleasing exhaust note when you accelerate, without the annoying hum that can make highway driving tiresome. The GH-GDB(E) designation indicates specific fitment for certain Subaru Impreza models equipped with the EJ20 engine, ensuring a direct fit without the need for extensive modifications.

When installing a cat-back exhaust, you're typically looking at a bolt-on process, though it's always a good idea to refer to the manufacturer's installation instructions for specific details. This HKS system is designed to integrate with your existing catalytic converter, making it a straightforward upgrade for many owners. The result is an improved exhaust note and a cleaner look under your vehicle.
