HKS LEGAMAX Premium Sports 5BA-RV37 400R MAIN

This is the HKS LEGAMAX Premium Sports cat-back exhaust system specifically for the 5BA-RV37 400R. If you're looking to give your 400R a more aggressive exhaust note and improved flow, this system is a solid choice. It replaces the factory muffler and piping from the catalytic converter back, changing the sound and performance characteristics of your vehicle's exhaust.

HKS has a long history with performance tuning, and the LEGAMAX Premium line is built with that experience in mind. This system is constructed from SUS304 stainless steel, which is known for its strength and resistance to corrosion, ensuring it holds up well over time. The piping diameter is optimized to work with the 400R's engine, aiming for a balance between increased exhaust flow and maintaining good low-end torque. You can expect a deeper, sportier tone that's noticeable without being overly intrusive for daily driving, and the polished finish on the tips adds a clean, performance-oriented look to the rear of your car.

When installing a cat-back system like this, it's a good idea to have a helper and ensure you have the necessary tools for unbolting the stock exhaust and mounting the new HKS components. While it's designed as a direct replacement, always refer to the manufacturer's installation instructions for specific details and torque specifications to ensure a proper and secure fit. This system is designed to bolt directly onto the factory exhaust flange behind the catalytic converter.
