Type 25 Exhaust Pipe - Silencer To Cast Elbow On Left Hand Side - 1985-87 - DJ, DF, DG Engine Codes

This centre exhaust pipe is designed to fit before the rear muffler on Volkswagen Type 25 / T3 buses manufactured from October 1985 to July 1987, fitted with 1900cc (DF, DG) or 2100cc (DJ) Waterboxer petrol engines.

The centre exhaust pipe forms a critical part of the exhaust system, carrying exhaust gases from the forward exhaust components into the rear silencer (muffler). Its role is to ensure smooth gas flow, reduce exhaust restriction, and allow the muffler to effectively reduce noise while maintaining correct engine back pressure. On Waterboxer engines, correct exhaust flow is essential for stable idle, clean acceleration, and proper engine temperature control.

Over time, the original centre pipes are prone to corrosion, cracking around joints, or internal restriction caused by rust buildup. These issues can lead to increased exhaust noise, power loss, exhaust leaks, and MOT failure. Replacing the centre exhaust pipe restores the integrity of the exhaust system and helps protect the rear muffler from excess stress caused by leaks or misalignment.

This replacement pipe is manufactured to the correct original shape and dimensions, allowing it to bolt directly into place using the existing exhaust layout. It is designed specifically for vehicles using the rear-mounted muffler system, ensuring correct alignment and fitment without modification.
