Description
When your old International starts sounding like a freight train and you’re getting looks from the neighbors, it’s time for a new muffler. A blown-out exhaust doesn’t just make noise—it lets engine fumes into the cab and can mess with back pressure, affecting how your tractor runs. This vertical muffler gets your IH tractor back to civilized sound levels so you can work in comfort.
What You’re Getting
- Oval body design that fits the original mounting points perfectly
- 34-inch length with proper inlet and outlet sizing for optimal exhaust flow
- Vertical orientation that keeps the exhaust stream away from the operator
- Heavy-gauge steel construction that handles the heat and vibration of farm work
- Direct replacement—no modifications or adapters needed
Built for Real Farm Work
This muffler is engineered for the mid-sized International tractors that handle everything from hay cutting to loader work. Whether you’re running a 454 utility tractor around the farmyard or pushing a 674 through heavy tillage, this muffler handles the exhaust flow these diesels produce while keeping noise down to reasonable levels.
Made to Last
Farm tractors don’t get babied, and this muffler is built accordingly. The steel construction resists corrosion from moisture and road salt, while the internal baffles are designed to handle the constant temperature cycling that comes with daily use. It’s the same quality replacement that’ll give you years of quiet operation.
Good to Know
Installation is straightforward—unbolt the old muffler and bolt on the new one using the existing mounting points. Before you start, spray the old clamps and bolts with penetrating oil—exhaust components tend to seize up over time. Check your exhaust pipe condition while you’re at it, as a new muffler on a rotted pipe won’t last long.
