- Downpipe for Audi A4 B5, A6 C5, 1.8T and Passat 1.8T made of stainless steel

Description:

- The downpipe is positioned between the catalytic converter and the exhaust system. It bolts to the original catalytic converter, or our plug&play 200-cell catalytic converter with the item number 340106 can be used. It has a cross-section of 63mm (original 54mm), includes an interlock flex pipe, and mounts are installed. The larger downpipe reduces back pressure, offloads the turbo, and can increase performance, depending on the installed components, up to 330HP. The pipe is bent and welded only at the flex piece and flange. To connect to the original exhaust system, a reduction sleeve from 63>54mm is needed, but usually, larger exhaust systems are used in tuning.
