# 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. The near-identical muffler 3886134 at 198.5 kg adds a spark arrestor, and that fitting is the only meaningful difference between the two.

## 🚤 Compatibility

-   **Engine Family:** D, TWD, TAD

## ⚙️ Key Features

-   7 inch connection
-   For dry exhaust installations
-   194.59 kg
-   64 applications across the D, TWD and TAD series
-   No spark arrestor, muffler 3886134 is the version with one

## 🔌 Function

Reduces exhaust noise in a dry exhaust installation while passing the full gas flow of the engine.

## ⚠️ Common Signs of Failure

-   Exhaust note noticeably louder or harsher than before
-   Soot staining or leaks at the flanged joints
-   Shell rusted through, blistered or holed
-   Internal baffles heard rattling or loose
-   Back pressure raised, showing as smoke and lost power

## 🛠️ 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
