HKS LEGAMAX Premium GVB/GVF (MAIN+CP)

If you're looking to give your Subaru WRX STI GVB or GVF a more aggressive sound and improved exhaust flow, the HKS LEGAMAX Premium cat-back system is a solid choice. This system replaces the factory piping from the catalytic converter back, including the muffler and mid-pipe, to enhance the driving experience. It’s designed to work with the specific layout of these models, aiming for a direct fit and a noticeable change in exhaust note.

HKS has built this system using SUS304 stainless steel for the main piping and muffler, which is well-known for its resistance to corrosion and its ability to handle the heat generated by an exhaust system. The design focuses on optimizing exhaust gas flow, which can lead to a more responsive feel and a deeper, sportier tone without being overly loud or droney. The system includes the main pipe section and the center pipe, ensuring a comprehensive upgrade from the catalytic converter back. You'll notice a distinct difference in sound, especially under acceleration, and a subtle improvement in how the engine breathes.

When installing a cat-back system like this, it's always a good idea to have a helper and to inspect all the hangers and mounting points on your vehicle. While this system is designed for a direct fit, ensuring everything is aligned properly will make the installation smoother and prevent any rattles or leaks. You'll want to check the manufacturer's instructions for any specific torque recommendations or alignment tips to get the best results from your new HKS exhaust.
