Vertical Exhaust Muffler for David Brown 770, 880, 885, 995, and 1200 Series Tractors

Description

When your David Brown starts sounding like a diesel locomotive and the neighbors are giving you dirty looks from three farms over, it’s time for a new muffler. A worn-out or rusted-through muffler doesn’t just make noise—it affects your engine’s back pressure and can impact performance. This vertical replacement muffler brings back the civilized sound levels these British workhorses were meant to have.

What You’re Getting

• Proper vertical orientation with 4-1/4″ body diameter for steady mounting
• Correct 1-7/8″ inlet fits your exhaust manifold without adapters or modifications
• 2″ outlet diameter maintains proper exhaust flow and back pressure
• 35″ overall length with quality internal baffling for effective sound reduction
• Round body construction handles the heat cycles and vibration these tractors produce

Built for Real Farm Work

David Brown tractors have a loyal following among farmers who appreciate their solid build quality and dependable performance. Whether you’re running a 50-horsepower 770 for hay work or powering through with an 880 series tractor on loader duty, these machines work hard day after day. This muffler is designed to handle that steady workload while keeping noise levels where they should be.

Made to Last

Farm mufflers take punishment from temperature extremes, road salt, barnyard chemicals, and constant vibration. This replacement uses heavy-gauge construction with proper internal baffling that won’t blow out under normal operating conditions. The vertical design sheds water better than horizontal units and keeps the mounting points from collecting moisture and debris.

Good to Know

This is a direct bolt-on replacement—no cutting, welding, or fabricating required. Before installation, check your exhaust manifold gasket and mounting studs for wear. Old exhaust components often seize together, so soak everything with penetrating oil the night before you plan to work on it. A new muffler on a cracked manifold or loose studs won’t solve your noise problems.
