Type 25 Exhaust Manifold (Cylinder 2 To 4) - 1986-92 - Waterboxer (DF, DG, DJ Engine Codes)

This replacement standard exhaust rear pipe is fitted between cylinders 2 and 4 on Volkswagen Type 25 / T3 buses manufactured from October 1985 to July 1992, fitted with 1900cc DF or DG and 2100cc DJ Waterboxer petrol engines.

Located at the rear section of the exhaust system, this pipe joins the exhaust outlets from cylinders 2 and 4 and directs exhaust gases towards the front muffler section. Correct routing and alignment at this point are essential for maintaining balanced exhaust flow, correct back pressure, and smooth engine operation on late Waterboxer models.

Manufactured as a standard mild steel replacement, this pipe is ideal for restoring the original exhaust layout or replacing rusted, cracked, or leaking factory components. It is formed to match the correct late Waterboxer exhaust layout and aligns with original mounting points for straightforward installation.
