# 21524954 Exhaust Pipe | Genuine Volvo Penta Part

## 🔧 Product Description

Three-and-a-half-inch exhaust transfer pipe used in Volvo Penta SCR/aftertreatment installations. It links the engine exhaust outlet, dosing and catalyst components in the original low-emission exhaust arrangement. The pipe is designed for the correct V-clamps, sensor positions and flow direction and is not the urea-resistant pipe used in alternate installations.

## 🔌 Function

Transfers hot exhaust gas through the dosing and catalyst assembly while maintaining sealed flow for correct emissions-system operation.

## ⚠️ Common Signs of Failure

-   Black soot around joints or V-clamps
-   Exhaust smell or noise in the engine compartment
-   Cracks, distortion or heat damage
-   SCR efficiency or exhaust-temperature faults
-   Loose sensor boss or damaged sealing flange

## 🛠️ Service Notes

-   Fit new gaskets and seals at every joint you disturb; exhaust gaskets take a set once they have been heat-cycled and will not seal a second time
-   Clean the flange faces back to bare, flat metal and check them for distortion and pitting — a warped face will blow out a new gasket however hard it is pulled up
-   Renew corroded studs and nuts, use a high-temperature anti-seize on the threads, and tighten in the sequence and to the figures in the workshop manual for your engine; recheck once the engine has been run up to temperature and allowed to cool, because the joint relaxes over the first few heat cycles
-   Support the pipe on its own mountings so nothing hangs on the flange and no hose pull is taken through the joint, and keep the specified clearance to hoses, wiring and glassfibre
-   On water-cooled sections, check the cooling passages are clear and the water connections sound before running — a restricted jacket will cook the pipe and the hose behind it
