Straightline Performance 134-169 Lightweight Carbon Fiber Snowmobile Exhaust Silencer

The Straightline Performance 134-169 Lightweight Carbon Silencer is a high-performance slip-on exhaust silencer engineered for Ski-Doo snowmobiles. Constructed with a full carbon-fiber body and stainless steel internals, this muffler delivers significant weight savings over OEM units while maintaining stock-level performance or better.

Designed for noise-conscious riding environments, this silencer produces a low, deeper exhaust tone while keeping peak and mid-range volume comparable to stock. In select applications, riders can expect a gain of 1–2 horsepower over the factory silencer — and all fitments are guaranteed to perform at least equal to OEM. The straight-can design installs using the stock exit location with no modifications required.

Key Features:

• Carbon fiber body — ultralight construction weighing just 2.6 lbs
• Fully rebuildable — designed for long-term serviceability
• One-piece internals for improved durability and sound consistency
• Stainless steel construction — corrosion-resistant for long service life
• Direct bolt-on fit — no modifications required, uses stock exit location
• Reduced exhaust note — engineered for noise-conscious riding environments
• Performance benefits — potential 1–2 HP gain in select applications
• Slip-on style — straight-can design for easy installation
