Downpipe for Audi A4, A6 1.8T B6, Passat 1.8T 3BG/5B, FWD, ø 63mm (2.5"), made of stainless steel

What’s Included:
- Stainless steel downpipe for Audi A4 B6, A6 1.8T, and Passat 1.8T with front-wheel drive (FWD)

Description:
- The downpipe is located between the catalytic converter and the exhaust system. It is bolted to the original catalytic converter, or you can use our plug-and-play 200-CPI catalytic converter (item no. 340106). It has a cross-sectional diameter of 63 mm (original: 54 mm), and an Interlook flexible pipe and bracket are included. The larger downpipe reduces backpressure, relieves the turbo, and allows for increased power output—up to 330 PS, depending on the components installed. The pipe is bent and welded only at the flex joint and flange. To connect to the original exhaust system, you’ll need to use a 63>54 mm reducer sleeve, but in most cases,larger exhaust systems are used during tuning.
