Oval Exhaust Muffler Box for Farm Tractors with 2-3/8 Inch Inlet and 3-3/4 Inch Outlet SKU: QT42185

When your tractor muffler fails, you don't just get loud exhaust—you get the kind of noise that makes every workday miserable and neighbors complain. This oval replacement muffler restores proper exhaust flow and civilized sound levels, protecting your hearing during long field operations.

Why This Design Works

• Oval body maximizes internal volume for superior sound dampening in tight underhood spaces
• Heavy-gauge steel construction resists rust-through from inside out where most mufflers fail
• Reinforced mounting flanges handle engine vibration without cracking
• Precision-sized inlet and outlet ensure proper exhaust flow for optimal engine performance

A blown-out muffler affects more than noise—it can disrupt exhaust back pressure and impact engine efficiency. When you're ready to restore quiet operation and protect your equipment investment, S&H Parts has the solution that fits right the first time.
