HKS LEGAMAX Premium GP7 FB20

This is the HKS LEGAMAX Premium cat-back exhaust system, specifically designed for the FB20 engine found in certain Subaru Forester models. If you're looking to give your Forester a more refined exhaust note and potentially a slight improvement in performance, this system is a solid choice. It replaces the factory muffler and piping from the catalytic converter back, offering a more direct path for exhaust gases.

HKS is well-known for its performance exhaust components, and the LEGAMAX Premium line aims for a balance between sporty sound and everyday drivability. This system is constructed from SUS304 stainless steel, which is strong and resists corrosion, helping it last a long time even in varied weather conditions. The design focuses on reducing backpressure compared to the stock setup, which can lead to a more responsive feel and a deeper, more satisfying exhaust tone without being overly loud or droney at cruising speeds. You'll notice the quality in the welds and the overall fit and finish, which are typical of HKS products.

When installing this cat-back system, you'll typically be bolting it up to your existing catalytic converter. It's designed as a direct replacement for the factory rear section, meaning no cutting or welding is usually required for installation. This makes it a more straightforward upgrade for many DIYers or a quicker job for a professional mechanic. The result is an improved exhaust note that complements the FB20 engine's character, making your Forester sound as good as it looks.
