- Downpipe for Audi A4 A6 1.8T B5 3B 3BG Quattro ø 63.5mm 2.5" made of stainless steel

Description:

- the downpipe is positioned between the catalytic converter and the exhaust system. It is bolted to the original cat or you can use our plug&play 200 cell cat with the article number 340106. It has a diameter of 63mm (original 54mm), includes an interlock flex pipe and brackets. By using the larger downpipe, back pressure is reduced, turbo is relieved, and more power can be achieved, depending on 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 reducer from 63>54mm needs to be used, but usually, larger exhaust systems are used for tuning.
