Armytrix Valvetronic Stainless Steel Cat-Back Exhaust System (OEM Valve Control) Toyota GR Supra A90

Transform the sound, performance, and character of your Toyota GR Supra A90/A91 with the Armytrix Valvetronic Stainless Steel Cat-Back Exhaust System. Designed as a direct bolt-on upgrade that integrates seamlessly with the OEM valve control system, this system delivers increased power, reduced weight, and a dramatically enhanced exhaust note.

Engineered with precision and developed for real-world driving, the Armytrix system improves exhaust flow and responsiveness, especially through the low- and mid-range. The result is a deeper, more aggressive tone under throttle, while maintaining refined acoustics during cruising.

Valvetronic Control – Quiet When You Want, Loud When You Need

Armytrix Valvetronic technology allows full control of exhaust valve operation via the factory ECU. When driving at low RPM, the valves close to maintain backpressure and keep noise levels neighbour-friendly. Under higher load or throttle, the valves automatically open to increase flow, boost performance, and unleash the signature Armytrix sound.

With the system’s intelligent auto-mode, owners can customise valve behaviour based on RPM or throttle input, giving complete flexibility between comfort and performance.

How Valvetronic Works

• Uses factory vacuum and ECU signals for seamless OEM-style behaviour.
• OBD-linked control communicates with the valve module for quick actuation.
• Open valves = maximum flow, sharper throttle response, and a louder, motorsport-inspired sound.
• Closed valves = quiet operation for early mornings or residential areas.
• Automatic valve strategies can be set by RPM or throttle to match your driving style.

On turbocharged vehicles such as the Supra A90/A91, opening the valves reduces backpressure and can increase turbo efficiency, contributing to additional power gains.
