When your International’s getting louder than a freight train and you’re tired of shouting over the racket just to talk to someone standing next to the tractor, it’s time for a new muffler. This vertical diesel muffler is built specifically for those big International workhorses with DT414, DT436, and DT466 engines that move serious dirt all day long.
What You’re Getting
- Oval body design maximizes sound dampening while fitting the tight engine compartment
- Heavy-duty construction built to handle the heat and vibration of diesel operation
- Precise inlet and outlet sizing ensures proper exhaust flow for optimal engine performance
- Vertical mounting orientation matches the original factory setup
- 44-inch overall length provides the internal volume needed for effective sound reduction
Built for Real Farm Work
These International tractors earned their reputation in heavy tillage, large-scale planting, and demanding field operations where reliability matters most. Your 1066 pulling a chisel plow or that 4366 running a 12-row planter generates serious exhaust pressure that needs proper handling. The oval shape gives you maximum internal volume for sound reduction while fitting the space available in these powerful machines.
Made to Last
Farm mufflers take abuse from temperature swings, moisture, and constant vibration. This replacement is engineered to handle the reality of diesel operation with internal baffling designed to resist collapse and steel construction that fights rust-through from the inside out. Quality materials and construction mean you won’t be doing this job again next season.
Installation Notes
This is a direct replacement that mounts vertically just like the original. Before you start, soak the old exhaust bolts with penetrating oil—they love to snap off when you’re in a hurry. Check your exhaust pipe condition while the old muffler is off, and replace gaskets to prevent leaks that defeat the purpose of a new muffler.
