MK4 TDI Downpipe – XS-POWER ALH 1.9 TDI Resonated Downpipe (1999-2005 Golf / Jetta / Beetle)

 

MK4 TDI Downpipe – XS-POWER ALH 1.9 TDI Resonated Downpipe (1999-2005 Golf / Jetta / Beetle)

Upgrade the exhaust system on your Volkswagen MK4 TDI with the XS-POWER Version 2 Resonated Downpipe, designed specifically for 1.9L ALH Turbo Diesel engines from 1999–early 2005.

This performance MK4 TDI downpipe improves turbocharger efficiency by reducing exhaust backpressure and increasing exhaust flow, helping the turbo spool faster while improving overall engine performance.

The integrated resonated section helps control exhaust tone and reduces unwanted drone, making it a quieter alternative to fully catless non-resonated downpipes while still delivering excellent performance gains.

Perfect for enthusiasts upgrading their MK4 Golf TDI, Jetta TDI, Bora TDI, or New Beetle TDI exhaust systems.
