GT1 Catback exhaust
RF Yamamoto - NSX
The RFY GT1 Exhaust is Racing Factory Yamamoto's masterpiece, engineered with a singular vision: to extract the absolute maximum performance from the NSX engine and deliver an unfiltered, exhilarating motorsport soundtrack. This is the system for the driver who prioritizes raw performance and a sound that stirs the soul.
Unlike systems that balance comfort and performance, the GT1 is unapologetically focused on the latter. It is a confident expression of what a race-bred exhaust should be, providing a direct connection between the driver, the engine, and the road.
Adjustable Sound via Removable Cartridge Baffles or Valve:
The core innovation of the GT1 system is its user-configurable sound profile. The mufflers are equipped with easily removable, cartridge-style baffles, giving the owner complete control.
- Baffles In: Delivers a deep, loud, and aggressive tone that is purposeful without being excessive.
- Baffles Out: Transforms the system completely, unleashing the raw, high-pitched, unbridled wail of the C-series V6, especially at high RPMs. This is the GT1 in its purest form.
- Optional valve: At A.S. Motorsport we often install a vacuum valve here to make it variable this allows you to switch from aggressive to loud
Engineering & Performance:
- Maximum Performance Concept: Engineered for maximum exhaust gas velocity and minimal backpressure, this system is designed to achieve the highest possible horsepower gains. It is the ideal companion for the RFY GT1 Headers.
- Uncompromised Racy Sound: The sound profile is sharp, clean, and directly inspired by the racetrack, delivering a signature F1-style scream at the top of the rev range.
- Lightweight Construction: Prioritizes lightweight materials and superior TIG-welded construction for durability under the most demanding driving conditions.
Customization Note: Single-Tip Outlet Option: For a unique and highly aggressive aesthetic, this system can be special-ordered with a single-outlet configuration. Please contact us to specify this option when placing your order.
