Exhaust Box Muffler for Non-Turbo Tractor Engines with 4-Bolt Flange Mount SKU: QT403990

When your tractor's exhaust starts roaring like a freight train and neighbors give you those looks, it's time for a new muffler. A failed exhaust box doesn't just create ear-splitting noise—it reduces engine efficiency and can lead to expensive damage from improper back pressure.

Why This Muffler Delivers

• Non-turbo design maintains proper back pressure for naturally aspirated engines
• Heavy-gauge steel construction resists rust-through from heat and moisture
• 4-bolt flange mount provides secure, vibration-resistant connection
• 32.3-inch length with 6.50-inch body diameter fits specific tractor configurations

Professional fitment ensures your tractor runs quietly and efficiently for years to come. At S&H Parts, we've been matching the right exhaust solutions to hardworking equipment since 1969.
