Walker 35514 Exhaust Rain Cap 2.5" Inlet — Heavy-duty truck protection, universal-fit

Walker Heavy Duty 35514 is a 2.5-inch inlet exhaust rain cap engineered to block water and debris from entering heavy-duty truck exhaust systems.

This rain cap from Walker is a purpose-built accessory for heavy-duty exhaust applications that helps protect tailpipes from rain, road grit, and nesting debris. It’s made to work with Walker Truck Staxx systems and other compatible exhaust lines, offering a straightforward way to preserve exhaust interiors and extend the life of downstream components. Designed as a universal-fit option, the 35514 is sold by inlet diameter and should be matched to the pipe ID for a secure fit.

How does the 35514 rain cap protect exhaust systems?

The rain cap forms a barrier at the pipe opening to prevent rainwater, leaves, and small objects from entering and stagnating inside the exhaust. By keeping moisture and contaminants out, it reduces the chance of internal corrosion and blockages that can complicate repairs.

• Rain-resistant hood prevents direct water entry into the tailpipe.
• Physical barrier keeps road debris and small animals out.
• Helps reduce interior corrosion risk by limiting moisture exposure.

The 35514 is sized by inlet (ID) and intended for a 2.5-inch diameter pipe; confirm your pipe inner diameter before ordering. It is compatible with Walker Truck Staxx systems and other universal-fit exhausts, but always verify vehicle-specific fit notes when available.

• Measure the inside diameter of the tailpipe — it must match 2.5" ID.
