GT-4 Catback exhaust
RF-Yamamoto - NSX
The RFY GT4 Catback system is Racing Factory Yamamoto's street friendly exhaust. It was engineered not simply as a replacement, but as a fundamental improvement, creating a driving experience that is both more comfortable and more exhilarating than stock.
This system is built on the concept of perfecting the dual nature of the NSX. It enhances low-end torque for more responsive city driving and eliminates cabin drone during highway cruising, achieving a level of comfort superior to the original. Yet, when you command it with the throttle, the GT4 awakens. It unleashes the pure, unadulterated sound of a high-performance sports car, realizing the acoustic potential that the manufacturer had to leave on the table.
Sound Profile:
The genius of the GT4 system is its refined, dual-character sound. At idle and low RPMs, it is civil and unobtrusive. Step on the accelerator, and the character transforms into a clean, crisp, and soulful exhaust note that builds into a thrilling wail through the VTEC crossover—all without the harshness or drone of lesser systems. It is the ideal sound for the discerning driver.
