Description

When your turbo Ford New Holland starts sounding like a freight train and the neighbors are giving you dirty looks, it’s time for a new exhaust box. This replacement muffler brings back the civilized sound levels your 40 Series tractor had when new. If your current muffler is rusted through, rattling with loose baffles, or just plain missing after years of hard work, this direct replacement gets you back to comfortable operation without the ear-splitting roar.

What You’re Getting

Internal baffling designed to handle the increased heat and flow from your turbo while providing effective sound reduction
Heavy-gauge steel construction that resists the accelerated corrosion from higher exhaust temperatures
Engineered to maintain proper back pressure – critical for turbo engines where too much restriction hurts performance but too little can damage the turbo
Direct replacement design eliminates modification requirements and reduces installation time

Built for Real Farm Work

Your Ford New Holland 40 Series tractor is a versatile agricultural workhorse used in diverse farming operations. These mid to high-horsepower tractors excel in row crop farming, hay production, livestock operations, and heavy field work including deep tillage, large implement operation, and commercial farming applications. These tractors pack serious power for their size, and turbos add their own unique exhaust note – which becomes a shriek when the muffler fails. You often work long hours during planting and harvest, and constant exposure to unmuffled turbo exhaust isn’t just annoying – it’s damaging to your hearing.

Made to Last

Turbocharged engines run hotter exhaust temperatures than naturally aspirated ones, and this muffler is built accordingly. The steel construction resists rust-through from the inside out – the most common failure mode for original mufflers. Turbo engines need proper exhaust flow to operate efficiently. A blown-out muffler can affect turbo performance and even lead to premature turbo failure from improper back pressure. This replacement box restores both the quiet operation and proper exhaust flow your turbo engine needs.

Installation Notes

Start by soaking old exhaust clamps and studs with penetrating oil well before the job – turbo exhaust heat makes these parts especially prone to seizing. Inspect your exhaust manifold and turbo outlet while you’re at it – cracks here are common on older turbo tractors and cause noise even with a new muffler. Use new gaskets and clamps for leak-free operation. Position the exhaust box to maintain proper clearance from hydraulic lines and wiring – turbo exhaust temperatures can damage nearby components.
