Straightline Performance Single Pipe – Arctic Cat Catalyst 858

The Straightline Performance Single Exhaust Pipe for the Arctic Cat Catalyst 858 is engineered for riders who demand more power where it matters most. This pipe delivers almost 10 horsepower gains while significantly broadening the powerband, especially at higher RPM, giving you stronger pull, quicker acceleration, and improved top-end performance.

Designed and tested by Straightline Performance, this pipe transforms how the Catalyst 858 delivers power. Whether you’re hammering the throttle on long pulls, pushing through deep snow, or riding aggressive trail conditions, the improved RPM range keeps the sled pulling hard without falling flat.

Unlike pipes that only chase peak numbers, this system focuses on usable power, creating a smoother, more responsive ride that feels stronger everywhere above mid-range RPM. The result is a sled that accelerates harder, revs freer, and stays in the power longer.

Built with high-quality materials and precision fabrication, the Straightline Performance Single Pipe offers a perfect balance of durability, weight savings, and performance — all while maintaining reliable engine operation.
