HKS SUPER TURBO MUFFLER GVB EJ20

If you're looking to get the most out of your EJ20 engine, especially if you've already made some modifications, the HKS SUPER TURBO MUFFLER cat-back exhaust system is a solid choice. This system is designed to improve exhaust flow and sound, helping your engine breathe easier and perform better. It replaces the factory exhaust from the catalytic converter back, offering a more direct path for exhaust gases to exit the vehicle.

HKS has a long history with performance tuning, and this muffler reflects that experience. It's constructed from SUS304 stainless steel, which is known for its strength and resistance to corrosion, meaning it should hold up well over time. The internal design of the muffler is focused on reducing backpressure while also creating a distinct, sporty exhaust note that's noticeable but not overly aggressive. This updated design aims for a balance between performance gains and a comfortable driving experience, avoiding excessive drone at cruising speeds. The piping diameter is optimized for the EJ20 engine to ensure efficient scavenging and a good powerband.

When installing this cat-back system, you'll typically find it's a direct bolt-on affair, replacing your stock muffler and connecting to your existing catalytic converter. It's a popular upgrade for Subaru WRX and STI owners looking for that signature HKS sound and a bit more performance. While this system focuses on the muffler and rear section, remember that other exhaust components like downpipes and headers can further enhance exhaust flow and engine output.
