Fi Exhaust Nissan GT-R R35 Race Version: Valvetronic Performance Guide

The Nissan GT-R R35 is a legendary supercar, revered globally for the immense capability of its VR38DETT engine. However, to truly match its blistering performance with an equally aggressive acoustic presence, upgrading the factory exhaust system is essential. For GT-R owners demanding the absolute pinnacle of sound and airflow efficiency, the **Fi Exhaust (Frequency Intelligent Exhaust) Race Version** is the ultimate solution.

Designed with motorsport-inspired engineering and advanced valved technology, this exhaust system offers a perfect balance between track-ready aggression and street-friendly refinement. In this technical review, JPM Automotive explores the architecture and dynamic benefits of the Fi Exhaust Race Version for the R35.

1. Intelligent Valvetronic Technology

The core innovation of the Fi Exhaust system is its advanced **Valvetronic** functionality, providing drivers with on-demand control over exhaust backpressure and sound volume.

* **Race Mode (Valve ON):** When the valves are fully open, exhaust gases bypass the muffler for a straight-through flow. This minimizes backpressure, allowing the turbochargers to spool faster and producing an intense, high-pitched motorsport soundtrack.
* **Street Mode (Valve OFF):** Closing the valves routes the exhaust gases through the muffler internals, significantly reducing sound volume and eliminating drone. This setting is perfect for low-profile, comfortable daily driving.
* **Advanced Control System:** Drivers can seamlessly switch between modes using a dedicated remote control. Additionally, upgrading to the Fi Pro App allows for automated valve operation based on engine RPM settings.

2. Premium Materials and Performance Architecture

Fi Exhaust prioritizes high-grade materials and fluid dynamics to ensure maximum durability and unimpeded exhaust flow.

* **Premium Construction:** Owners can select between high-grade T304 Stainless Steel for exceptional durability or ultra-lightweight Titanium to drastically reduce the vehicle's overall curb weight while maintaining immense structural strength.
* **Optimized Exhaust Flow:** The entire system—including the Y-Pipe, Mid-Pipe, and Valvetronic Muffler—features thick pipe walls and a polished interior. This design prevents raspy frequencies and ensures the smoothest possible evacuation of exhaust gases.
* **Precision Bolt-On Fitment:** Engineered specifically for the Nissan GT-R R35, the system mounts directly to factory hanger locations, ensuring a flawless, direct bolt-on installation without requiring chassis modifications.

Who Is This Upgrade For?

* **Nissan GT-R R35 Owners:** Drivers seeking to maximize the breathing efficiency of their twin-turbo V6 and sharpen throttle responsiveness.
* **Sound Enthusiasts:** Those who desire a high-pitched, exotic exhaust note for spirited driving but require a quiet mode for neighborhood cruising.
* **Track Day & Performance Builders:** Enthusiasts looking to shed weight (especially with the titanium option) and optimize high-RPM exhaust flow for maximum engine output.

Things to Consider

* **Downpipe Upgrades:** To extract maximum performance and the most aggressive sound profile, consider pairing the catback system with ultra-high-flow or catless downpipes. Note that upgrading downpipes typically requires custom ECU software calibration to ensure optimal engine performance.
* **Exhaust Tip Customization:** Fi Exhaust offers multiple premium finishes for the quad exhaust tips, including Titanium Blue, Diamond Black, and Carbon Fiber. Select a finish that complements your GT-R's exterior styling.

Conclusion

The **Fi Exhaust Nissan GT-R R35 Race Version** is far more than a simple sound modifier. It is a highly engineered performance component that seamlessly blends optimal exhaust flow, weight reduction, and intelligent sound control. This system provides the ultimate acoustic and dynamic upgrade, allowing your GT-R to truly roar on command.
