Description

When your Maxxum starts sounding like it’s missing its muffler and the neighbors are giving you looks from three fields over, it’s time for a new exhaust box. This replacement muffler for Case IH Maxxum 5120 and 5220 models brings back the civilized sound levels these hardworking tractors had when new, letting you actually have a conversation while you work instead of shouting over the roar.

What You’re Getting

Direct replacement exhaust box that fits your Maxxum perfectly without modifications
Heavy-gauge steel construction that resists rust-through from the inside out
Internal baffling designed to handle farm work conditions and last for years
Proper mounting flanges that won’t crack under vibration like cheaper alternatives

Built for Real Farm Work

Your Maxxum 5120 or 5220 is the kind of mid-size workhorse that handles everything from loader work around the farmyard to pulling planters and cultivators in the field. These 75-90 horsepower tractors often work long hours during busy seasons, and constant exposure to unmuffled exhaust isn’t just annoying—it’s hard on your hearing and can indicate exhaust system problems that affect engine performance.

Made to Last

Farm exhaust systems take a beating from heat, vibration, and weather exposure. This exhaust box features steel construction that resists rust-through from the inside out—the most common way original mufflers fail. The internal components are built to withstand the constant heat cycles and exhaust flow these engines produce during demanding field operations.

Installation Notes

Before starting, soak the old exhaust clamps and mounting hardware with penetrating oil to prevent broken bolts. Check the condition of your exhaust pipe while you’re replacing the muffler—if it’s paper-thin or showing holes, replace it now rather than doing this job twice. New gaskets are cheap insurance against leaks that’ll defeat the purpose of your new exhaust box.
