Downpipe for Audi A4 A6 1.8T B6, Passat 1.8T 3BG/5B ø 63mm 2,5" made of stainless steel

- Stainless steel downpipe for Audi A4 B6 A6 1.8T and Passat 1.8T

Description:

- The downpipe sits between catalytic converter and exhaust system. It screws onto the original cat or our plug&play 200 cells cat with the Article No. 340106 can be used. It has a diameter of 63mm (original 54mm), an Interlook Flex pipe and brackets are installed. By using the larger downpipe, backpressure is reduced, turbo is relieved and more performance can be achieved, depending on the components installed, up to 330HP. The pipe is bent and welded only at the flex piece and flange. To connect to the original exhaust system, a reducer from 63>54mm is needed, but larger exhaust systems are mostly used in tuning.
