T4 Syncro Exhaust Centre Box (SWB Models)

Replacement intermediate exhaust pipe for Volkswagen T4 Transporter Syncro short wheelbase models. Designed to fit between the front exhaust section and rear silencer, this centre exhaust pipe restores correct exhaust flow, reduces blowing exhaust leaks and helps maintain proper engine performance and noise control.

Suitable for Syncro four-wheel drive T4 models fitted with selected 2.4 diesel and 2.5 petrol or diesel engines. The Syncro exhaust system differs from standard 2WD models due to the drivetrain layout, so correct fitment for SWB Syncro applications is essential.

Over time, original intermediate pipes can rust internally and externally due to heat cycles, moisture and road salt. Corrosion or damaged joints can lead to excessive exhaust noise, vibration, reduced fuel efficiency and MOT failures. Replacing worn exhaust sections helps restore smooth exhaust flow and reliable operation.
