Ski-Doo Gen 4 / Lynx 900 ACE Turbo Vari-Sound Muffler (Stainless Steel Electronic Controlled)

Product Description

Introducing the industry’s first electronically controlled exhaust system for the Ski-Doo 900 ACE Turbo platform. The Straightline Performance Vari-Sound Muffler gives riders complete control over their exhaust sound and performance with the simple push of a button.

Designed specifically for Ski-Doo 900 ACE Turbo, 900 ACE Turbo R, and Lynx models, this innovative system delivers a proven 2–3 horsepower gain while reducing overall vehicle weight by approximately 6 pounds compared to the factory exhaust system.

The Vari-Sound Muffler allows riders to instantly choose between two exhaust paths. In the closed position, exhaust flows through the Straightline Performance muffler, producing a quiet, refined tone ideal for trail riding and noise-sensitive environments. With the push of the included wireless remote, the electronically controlled valve opens, allowing exhaust to exit directly through a dedicated outlet, creating a significantly more aggressive sound and freer-flowing exhaust path.

This one-of-a-kind system delivers the best of both worlds—quiet operation when desired and aggressive performance sound when conditions allow.

Every kit includes all necessary components for installation, including the electronic valve system, wireless remote control, wiring harness, mounting hardware, and a precision aluminum trim ring designed to provide a clean, factory-quality finish when modifying the side panel for the exhaust outlet.

The system utilizes a simple plug-and-play electrical connection using the vehicle’s accessory power source, making installation straightforward and reliable. All electronics are designed for durability and long-term performance in harsh snowmobile environments.

If you’re looking for one of the most innovative exhaust upgrades available for the 900 Turbo platform, the Straightline Performance Vari-Sound Muffler delivers unmatched versatility, sound control, and performance.
