- Downpipe for Audi A4 A6 1.8T B6, Passat 1.8T 3BG/5B ø 76mm 3" made of stainless steel

Description:

- the downpipe is located between the catalytic converter and the exhaust system. It is screwed to the original catalytic converter or our plug&play 200 cell catalytic converter with the item number 340106 can be used. It has a diameter of 76mm (original 54mm), an Interlock flex pipe and brackets are installed.

The pipe is bent and welded only on the flex piece and flange. To adapt to the original exhaust system, a reducer sleeve from 76>54mm is used, but usually larger exhaust systems are used for tuning.
