Construction & Design:

The Legamax Sports Exhaust is crafted from premium SUS304 stainless steel, known for its excellent corrosion resistance and durability under high-temperature conditions. The exhaust features a straight pipe layout with a larger diameter main pipe to optimize exhaust gas flow and reduce back pressure, which can enhance engine responsiveness and efficiency.

The muffler’s internal silencer design and tailpipe configuration are meticulously engineered to produce a balanced sound profile that is both sporty and comfortable. This design ensures that the exhaust note intensifies naturally with engine RPM, providing an engaging auditory experience without excessive cabin noise at idle or low speeds.

Performance & Sound

This exhaust system significantly improves exhaust efficiency by expanding the pipe diameter and employing a straight layout, which helps the FA24 engine breathe more freely compared to the stock setup. The result is a noticeable enhancement in throttle response and overall engine performance.

Sound levels measured at idle remain consistent with stock at 56 dB, ensuring no intrusive noise during normal driving. However, the exhaust proximity noise increases from 83 dB stock to 89 dB with the HKS system, delivering a more aggressive and sporty tone that rises dynamically with engine speed. This sound character perfectly complements the vehicle’s Active Sound Control System, providing an exhilarating yet refined driving soundtrack.
