3886131 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta muffler with a 7 inch connection for dry exhaust, from the Inlet and Exhaust System group, weighing 194.59 kg and listed for 64 applications across the D, TWD and TAD series.

⚠️ Common Signs of Failure

• Shell rusted through, blistered or holed
• Internal baffles heard rattling or loose

🛠️ Service Notes

• Confirm whether the installation requires a spark arrestor before ordering, since 3886134 is the arrestor-equipped version of the same 7 inch dry muffler
• Check and renew the mounting and support brackets, as a 194.59 kg muffler that is poorly supported will crack its joints
• Renew the flange gaskets and fasteners on refitting
