This Straightline Performance Vari-Sound Muffler is an electronically controlled exhaust system for the Ski-Doo Gen 4 and Gen 5 and Lynx 850 Turbo platform, letting you switch between a quiet, trail-friendly tone and a freer-flowing performance exhaust with the included wireless remote. In quiet mode exhaust routes through the muffler for a deep, refined sound, while performance mode redirects it through a dedicated outlet for a more aggressive turbo note and increased flow.

Built from premium stainless steel with an aluminum heat shield wrap, it uses a proprietary turbo outlet design with full stainless steel diverter splitters, and the plug-and-play harness connects to the machine's accessory power for direct bolt-on installation using stock mounting locations. The kit includes the muffler, electronic valve assembly, wireless remote, wiring harness, stainless steel mounting hardware, and installation instructions, and it works on both stock and modified 850 Turbo machines.
