Scope of delivery:
- Downpipe for Audi A4 A6 1.8T B6 Quattro ø 76mm 3" made of stainless steel with Interlock flex pipe

---

Description:
- The downpipe sits between the catalytic converter and the exhaust system. It is screwed to the original catalytic converter, or our plug & play 200 cell cat with item no. 340106 can be used. It has a cross-section of 76mm (original 54mm), an Interlock flex pipe is installed. The larger downpipe reduces backpressure, relieves the turbo, and more power can be achieved depending on the installed components, up to 450 hp. The pipe is bent and welded only at the flex piece and flange. To fit the original exhaust system, a reduction from 76>54mm must be used, but most of the time larger exhaust systems are used in tuning.
