Show original supplier description
The Armytrix Titanium 90mm Valvetronic Cat-Back exhaust system is engineered to push the boundaries of performance for the 2009-2017 Nissan GT-R (R35). Constructed from premium titanium with 90mm piping, this system is designed to significantly increase exhaust gas surge quantity and speed without compromising efficiency. Its streamlined design is lighter than stock, weighing 22.1kg less, and offers an unrestrictive flow, contributing to dramatic improvements in both horsepower (+24.6 HP) and torque (+60.4 Torque). Technology-wise, the valvetronic system introduces a new dimension of versatility, allowing users to choose between a stealthy quiet mode or a thunderous performance sound via a wireless remote control. An exclusive OBDII dongle system simplifies installation and provides a user-friendly smartphone app interface to monitor the vehicle's real-time operational status and control valve settings. Crafted with meticulous attention to detail, Armytrix utilizes the skills of veteran artisans to ensure perfect fitment and exceptional quality. Each weld is administered by steady hands, creating a robust and reliable exhaust backbone. **Important Installation Note:** For the 2017 GT-R model, it is necessary to reattach the EV motors before starting the engine after installation. Failure to do so risks damaging the sensors due to exposure to moisture and external agents, which can cause irreparable harm to basic operational functions.
