About this part

Product Details

If you're looking to get more out of your GC8 with an EJ20 engine, a cat-back exhaust system like the HKS Hi-Power 409 can make a notable difference. This system replaces the factory exhaust from the catalytic converter back, improving exhaust flow and giving your car a more aggressive sound. It's designed to work with the stock catalytic converter, making it a popular choice for those wanting an exhaust upgrade without altering emissions equipment.

The Hi-Power 409 is constructed from SUS304 stainless steel, which is known for its strength and resistance to corrosion, ensuring it holds up well over time. HKS uses a large-diameter, straight-through muffler design. This setup minimizes backpressure, which can help your EJ20 engine breathe a little easier. You'll likely notice an improved throttle response and a deeper, sportier exhaust note that's more pronounced than the stock system, especially under acceleration. The piping diameter is optimized for the EJ20 engine to balance performance gains with drivability.

Installation of a cat-back system is generally straightforward, often bolting directly to the existing hangers and connections. This HKS system is designed to fit right, simplifying the process for a mechanic or a DIYer. While it's designed to work with the stock catalytic converter, it's always a good idea to check local regulations regarding exhaust modifications. This cat-back system is a solid option for GC8 owners looking for a well-built exhaust that enhances both sound and performance.
