Type 25 Stainless Exhaust Pipe - From CAT To Exhaust Manifolds - 1983-85 - Waterboxer (DH + DJ Engine Code)

This stainless steel exhaust centre pipe fits between the exhaust manifold and the catalytic converter on Volkswagen Type 25 / T3 buses manufactured from 1983 to 1985, fitted with 1900cc DH and 2100cc DJ Waterboxer petrol engines.

Located in the centre section of the exhaust system, this pipe carries exhaust gases directly from the engine manifold into the catalytic converter. Correct fitment and internal diameter are essential at this point in the system to maintain proper exhaust flow, engine efficiency, and emissions performance on early Waterboxer models.

Manufactured from high-quality stainless steel, this pipe offers excellent resistance to corrosion and heat, making it a long-lasting upgrade over original mild steel components which are prone to rust and failure. Stainless construction is ideal for vehicles used regularly, stored outdoors, or undergoing long-term restoration.

This exhaust pipe is formed to match the early Waterboxer exhaust layout, ensuring correct alignment with the manifold, catalytic converter, and original mounting points. It is a direct-fit replacement, allowing straightforward installation without modification.
