T4 Transporter Exhaust Centre Box - SWB - 1996-03 (AAC,AES,ACU,AET,APL,AVT Engines)

This replacement intermediate exhaust box (middle silencer) is designed specifically for short wheel base (SWB) Volkswagen T4 Transporters fitted with petrol engines. Manufactured to the correct SWB length, it provides a direct-fit solution when replacing a corroded or noisy original exhaust section, restoring proper exhaust flow and factory-level noise control.

What this part does

The middle exhaust silencer reduces exhaust noise while maintaining correct exhaust backpressure. Positioned between the front exhaust section and rear silencer, it plays a key role in overall exhaust system performance. A failed or rusted silencer can cause excessive noise, rattles, exhaust leaks, and reduced engine efficiency.

How it works

As exhaust gases pass through the silencer chambers, sound waves are dampened while gases continue to flow smoothly through the system. This design keeps noise levels under control without restricting performance, ensuring smooth engine operation and comfortable driving—especially important on longer journeys.
