Description
When your International’s muffler starts sounding like a freight train and you can hear it from three fields over, it’s time for a replacement. This horizontal oval muffler brings back the civilized sound levels your 1086, 1486, or 1586 had when it rolled off the line, so you can work comfortably without waking the neighbors or damaging your hearing during those long days in the field.
What You’re Getting
- Horizontal oval body design that matches your tractor’s original exhaust configuration
- 3-5/8 inch inlet diameter and 3-1/4 inch outlet diameter for proper exhaust flow
- 15-1/2 inch overall length fits perfectly in the original mounting location
- Heavy-duty construction built to handle the heat and vibration of hard farm work
Built for Real Farm Work
This muffler is designed specifically for International’s big row-crop tractors—the 1086, 1486, and 1586 models that were workhorses in fields across America. Whether you’re pulling a 12-bottom plow, running a heavy cultivator, or handling harvest duties with a grain cart, these tractors put out serious power and need a muffler that can handle the exhaust flow and temperatures that come with it.
Made to Last
Farm mufflers take a beating from constant heat cycles, road debris, and the inevitable bump from tree branches or equipment. This replacement is built with the same oval body design as your original, using materials that resist rust-through and maintain proper exhaust flow even after years of exposure to the elements.
Installation Notes
This is a direct replacement for your factory muffler—no modifications or adapters needed. Before installation, check your exhaust pipe condition and replace clamps if they’re corroded. A little penetrating oil on the old clamp bolts makes removal much easier, especially if they’ve been on there for years.
