Description
When your old International starts barking like a drill sergeant during morning chores, it’s time for a new muffler. This vertical muffler brings back the civilized exhaust note these classic gas-powered workhorses had when they rolled off the factory floor. If you’re tired of the neighbors complaining or having to shout over the engine noise, this direct replacement gets you back to comfortable operation.
What You’re Getting
- Factory-style vertical design mounts just like the original
- 22-inch overall length with 6-inch round body for effective sound dampening
- Proper inlet and outlet sizing – 3-1/8 inch inlet ID and 3-inch outlet OD for perfect fit
- Built specifically for C335 and C350 gas engines – no modifications needed
Built for Real Farm Work
This muffler was engineered for the International Harvester tractors that built American agriculture – the WD9 and WDR9 series, plus the 600 and 650 models. These were the tractors pulling plows through prairie sod, powering threshing machines during harvest, and handling the heavy lifting on farms from the 1940s through the 1960s. Whether you’re still using yours for daily work or showing it at tractor pulls, this muffler maintains that authentic appearance and sound.
Made to Last
These classic Internationals were built when things were made to last, and this replacement muffler follows that same philosophy. The steel construction handles the heat cycles and vibration that come with gas engine operation, while the internal baffling provides long-term sound reduction without breaking down over time.
Installation Notes
This is a direct bolt-on replacement for your original vertical muffler. The mounting points line up exactly with your existing exhaust system. Before installation, check your exhaust pipe for rust-through – it’s a good time to replace any questionable pieces while you’ve got everything apart.
