Type 25 Stainless Exhaust Manifold (Cylinder 1 To 3) - 1983-85 - Waterboxer (DH, DJ Engine Codes)

This stainless steel exhaust front pipe fits between cylinder 1 and cylinder 3 on Volkswagen Type 25 / T3 buses manufactured from January 1983 to July 1985, fitted with 1900cc DH and 2100cc DJ Waterboxer petrol engines.

Located at the front of the exhaust system, this pipe joins the exhaust outlets from cylinders 1 and 3 and directs exhaust gases towards the front muffler section. Correct fitment at this point is essential for maintaining proper exhaust flow, balanced back pressure, and smooth engine operation on early Waterboxer models.

Manufactured from high-quality stainless steel, this front exhaust pipe offers excellent resistance to corrosion, moisture, and heat, making it a long-lasting upgrade over original mild steel pipes which commonly rust and fail with age. Stainless construction is ideal for vehicles used regularly, driven year-round, or undergoing long-term restoration.

Formed to match the early Waterboxer exhaust layout, this pipe is a direct-fit replacement, aligning correctly with the cylinder head outlets, front muffler section, and original mounting points for straightforward installation without modification.
