Description
Description
This Straightline Performance Y-pipe manifold is a direct bolt-on upgrade for the Arctic Cat Catalyst 858 platform, including M 858, Riot 858, and ZR 858 models. It delivers a proven 2 horsepower gain and increased mid-range torque, so you get stronger acceleration and sharper throttle response where you actually ride.
The high-temp black coating protects against extreme exhaust temperatures and harsh conditions, and the manifold installs as a direct replacement with no fuel, clutching, or calibration changes required when used on its own.
