T4 Exhaust Front Pipe - Diesel Models (With CAT)

This front exhaust pipe is a direct replacement for Volkswagen T4 diesel models fitted with a factory catalytic converter. Positioned between the exhaust manifold/downpipe and the catalytic converter, the front pipe channels exhaust gases efficiently into the emissions system while maintaining correct back pressure and flow.

Manufactured to the original factory shape and bore size, this pipe ensures proper alignment with the catalytic converter and downstream exhaust components. It is suitable for both Short Wheel Base (SWB) and Long Wheel Base (LWB) vehicles, making it ideal for vans, buses, and platform/chassis variants used in commercial, camper, or utility applications.

A worn or leaking front pipe can cause excessive noise, exhaust fumes, poor emissions performance, and MOT failure. Replacing it restores correct exhaust flow, reduces vibration, and ensures the catalytic converter operates as intended.
