Scope of delivery:
- Stainless steel downpipe for Audi A4 B6 A6 1.8T and Passat 1.8T

---

Description:
- The downpipe is located between the catalytic converter and the exhaust system. It is bolted to the original catalytic converter, or our plug&play 200-cell cat with item no. 340106 can be used. It has a diameter of 63mm (original 54mm), an Interlook flex pipe, and brackets are installed. The larger downpipe reduces backpressure, eases turbo stress, and allows for more power output, up to 330hp depending on installed components. The pipe is bent and only welded at the flex section and flange. To connect to the original exhaust system, a 63>54mm reducer sleeve must be used, but most often largerexhaust systems are used in tuning.
