Description
When your Case starts sounding like a freight train instead of the reliable workhorse it should be, this replacement muffler brings back the quiet operation and proper exhaust flow your engine needs. The oval-body design was specifically engineered for these Case models, and proper exhaust function isn’t just about noise—it affects engine performance and makes those long days on the seat a lot more comfortable for your ears.
What You’re Getting
- Oval body construction with vertical orientation that matches your original setup
- 4-inch inlet diameter and 4-1/8-inch outlet that ensures proper exhaust flow
- 31-inch overall length with bent aspirator tube for correct positioning
- Secure 3-bolt mounting bracket that anchors solidly to your tractor
Built for Real Farm Work
This muffler is designed specifically for Case 3294, 3394, and 3594 tractors—versatile utility machines that handle everything from loader work to cultivation. Whether you’re moving hay bales, running a brush hog, or working around livestock, these tractors need exhaust systems that can handle the daily grind without falling apart.
Made to Last
The oval body design isn’t just for looks—it provides excellent sound dampening while handling the heat and vibration these engines produce. The heavy-gauge steel construction resists corrosion from moisture and road salt, and the mounting bracket is built to stay secure even when bouncing across rough fields.
Installation Notes
This is a direct replacement that bolts right up using your existing mounting points. The aspirator tube comes pre-bent to the right angle, so you won’t need to modify anything. Make sure to use new gaskets and check that exhaust clamps are properly tightened—loose connections cause noise and can damage the muffler over time.
