Vandemon Yamaha GEN4 MT-09 / FZ-09 / XSR900 / XSR900 GP Stealth Titanium Exhaust System (2021-2025)

Description

Experience the ultimate CP3 exhaust upgrade with the Vandemon Stealth Titanium Exhaust System. Designed specifically for the Yamaha MT-09, XSR900 and XSR900 GP, this innovative full titanium exhaust features Vandemon's exclusive Stealth Bimodal Technology, allowing riders to switch between a quieter muffled mode and a fully unrestricted race mode at the press of a button. Constructed entirely from premium Ti1 titanium, the system dramatically reduces weight while improving horsepower, torque and throttle response. A custom plug-and-play wiring loom is included, enabling simple installation without cutting or modifying the factory wiring harness. The Stealth system eliminates the restrictive OEM catalytic converter and unlocks the distinctive sound of Yamaha's CP3 triple-cylinder engine while giving riders the flexibility to choose between everyday riding comfort and maximum race-inspired performance.

This makes it one of the most unique premium exhaust systems available for Yamaha's CP3 platform.
