What is the primary benefit of a cat-back exhaust system?

A cat-back exhaust system replaces the factory exhaust components from the catalytic converter back. This typically results in improved exhaust flow, a sportier engine sound, and can offer a slight increase in performance.

What material is the HKS LEGAMAX Premium exhaust made from?

This exhaust system is constructed from SUS304 stainless steel. This material is chosen for its excellent resistance to rust and corrosion, which helps ensure a long lifespan for the exhaust system, especially in varying weather conditions.

Does this exhaust system come with a catalytic converter?

No, this is a cat-back exhaust system, which means it is designed to connect to your vehicle's existing factory catalytic converter. It replaces the exhaust piping and muffler assembly behind the catalytic converter.

Product Details

If you're looking to get more out of your Impreza GRB's EJ20 turbo engine, the HKS LEGAMAX Premium cat-back exhaust system is a solid choice. This system replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and deliver a more satisfying engine note. It's designed to work with your existing factory catalytic converter, making it a straightforward upgrade for those who want a better sound and potentially a bit more responsiveness without altering emissions equipment.

Crafted from SUS304 stainless steel, this exhaust is built to last. Stainless steel is well-known for its resistance to corrosion, which is crucial for an exhaust system that's constantly exposed to heat and the elements. The LEGAMAX Premium line is HKS's approach to balancing performance with a refined sound. You can expect a deeper, sportier tone that's noticeable during acceleration but remains comfortable for daily driving, avoiding excessive drone. The piping diameter is optimized to work with the EJ20 turbo engine, ensuring that backpressure is managed effectively for improved performance without sacrificing low-end torque.

This cat-back system is designed as a direct replacement for your stock exhaust, meaning it should bolt up to the factory hangers and connections. While it's a cat-back system, meaning it doesn't require cutting or welding for installation, it's always a good idea to have the right tools on hand and refer to the manufacturer's instructions for the best results. This HKS exhaust is a well-built option for Impreza owners looking for an improved exhaust experience.
