Type 25 Exhaust Knuckle - Left - From 4th Cylinder Silencer - 1983-85 - Waterboxer (DF, DG Engine Codes)

This replacement exhaust front pipe is located between the cylinder head and the exhaust system on the left-hand side of the engine on Volkswagen Type 25 / T3 buses fitted with 1900cc Waterboxer engines.

Positioned at the front section of the exhaust system, this pipe carries exhaust gases directly from the cylinder head into the rest of the exhaust assembly. Correct fitment at this point is critical to ensure proper exhaust sealing, correct back pressure, and smooth engine operation. A damaged or leaking pipe here can lead to exhaust noise, loss of performance, or heat damage to nearby components.

Manufactured as a quality reproduction, this exhaust pipe is formed to match the original factory shape and routing. It is designed as a direct-fit replacement, aligning correctly with the cylinder head outlet and the adjoining exhaust components without modification.
