Heat Resistant Exhaust Muffler Box for Massey Ferguson 390T, 398, and 698 Tractors

Description

When your Massey Ferguson 390T, 398, or 698 starts sounding like a freight train instead of the smooth-running workhorse it used to be, it’s time to look at that exhaust box. This heat-resistant black exhaust muffler brings back that civilized sound level that lets you actually think while you work. A blown-out muffler isn’t just noisy—it affects engine performance and can damage nearby components with excessive heat.

What You’re Getting

• Heat-resistant black coating that stands up to high exhaust temperatures without peeling or fading
• Internal baffling system designed to reduce noise while maintaining proper exhaust flow for engine performance
• Heavy-duty steel construction built to handle the constant vibration and heat cycling of tractor operation
• Direct replacement design that fits perfectly without modifications or adapters
• Mounting points engineered to handle years of field work without cracking or loosening

Built for Real Farm Work

Your 390T, 398, or 698 handles diverse agricultural tasks from cultivation and planting to hay operations, and these mid-size utility tractors often accumulate serious hours in tough conditions. Whether you’re running a disc harrow, operating a hay baler, or doing loader work around the farmyard, a properly functioning muffler keeps the work environment bearable and protects your hearing during those long days.

Made to Last

The heat-resistant coating on this muffler helps it withstand the constant high temperatures that destroy cheaper alternatives. The steel construction resists rust-through from the inside out, and internal baffling is designed to last, not collapse after a few seasons like inferior mufflers. This isn’t a universal part forced to fit—it’s engineered specifically for these Massey models.

Good to Know

Let the engine cool completely before starting work, as exhaust components get extremely hot during operation. Start by soaking mounting bolts with penetrating oil the day before—exhaust hardware loves to snap off when you’re in a hurry. Check the condition of your exhaust pipe while the old muffler is off and replace it now if it’s paper-thin rather than doing this job twice. Use new gaskets for a leak-free installation that’ll keep this muffler working quietly for years to come.
