This 3 inch exhaust pipe rain cap is designed for straight stack exhaust systems to help reduce the entry of rain, snow, and debris into the exhaust pipe. The flip-top design opens naturally with exhaust flow and closes when the engine is off, helping protect the exhaust system during operation and storage. Featuring a universal fit with a 3” inlet (inside diameter), this rain cap is suitable for a wide range of vertical exhaust pipe applications. Installation is quick and simple—just place the cap onto the top of the exhaust pipe and tighten the bolt securely. No special tools or modifications are required. Each package includes one exhaust rain cap, making it a practical choice for replacement, maintenance, or custom exhaust setups. Designed for use on straight stack exhaust pipes only. Please confirm pipe size before purchase to ensure proper fit.
