Is your Arctic Cat Wildcat exhaust leaking or sounding rattly? This graphite donut gasket is a common wear item that seals the connection between the muffler and the exhaust pipe. It's made by Caltric specifically for the 2012-2016 Wildcat 4, 4X, and X 1000 models. The dimensions are 56.2mm outer diameter, 13.4mm wide, and 7.4mm thick. It's made from durable graphite material that can handle high heat and creates a good seal. Replacing a worn-out gasket can fix exhaust leaks, reduce noise, and help maintain proper backpressure. This is a single gasket, comes with a 90-day warranty, and matches OEM numbers 0412-256 and 0412-375. A simple, inexpensive part that can make a big difference in your side-by-side's performance and sound. (California Prop 65 warning applies.)
