⚙️ Key Features

• 7 inch connection
• For dry exhaust installations
• With spark arrestor
• 198.5 kg
• 42 applications across the D series

🔌 Function

Silences the dry exhaust while its arrestor traps carbon and sparks carried in the gas stream.

⚠️ Common Signs of Failure

• Exhaust louder than usual or with a changed note
• Sparks or glowing carbon visible at the outlet
• Back pressure and lost power as the arrestor blocks with soot
• Shell corroded through or blistered by heat
• Soot leaks or staining at flanged joints

🛠️ Service Notes

• The spark arrestor is the only real difference from muffler 3886131, and less than 4 kg separates them, so order by whether an arrestor is required
• Service the arrestor element rather than leaving it to block, since a clogged arrestor raises back pressure and costs power
• Support the muffler at its designed mountings, as 198.5 kg hanging on the flanges will crack them

📦 Condition
