Product Details

If you're looking to get more out of your GRB EJ20 Turbo engine, a cat-back exhaust system like the HKS LEGAMAX Premium is a solid choice. This system replaces the factory exhaust from the catalytic converter back, which can help your engine breathe a little easier. It's designed to give you a sportier exhaust note and potentially improve throttle response by reducing backpressure.

HKS has a long history with performance parts, and this LEGAMAX Premium system is built with their experience in mind. 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 piping diameter is carefully chosen to balance exhaust flow with maintaining good low-end torque, a common consideration when upgrading exhaust systems on turbocharged cars. You'll notice a more aggressive, but still refined, sound compared to the stock muffler, especially when you get on the throttle. This system is designed as a direct replacement for the factory unit, aiming for a straightforward installation process without needing major modifications.

When installing a cat-back system, it's always a good idea to have a helper and some basic tools on hand. While this system is designed to fit, checking the manufacturer's installation guide for any specific torque recommendations or alignment tips is always recommended. You're looking for a noticeable change in sound and a more responsive feel from your EJ20 Turbo.
