Item no: 220175-S

Scope of delivery:
- Stainless steel downpipe for Audi A4 B7 1.8 TFSI FWD

---

Product description:
- The downpipe is located between the turbocharger and the exhaust system. It is bolted to the original turbocharger. It has a cross-section of 80 mm in the upper section, two M18x1.5 mm connections for the lambda sensor, and, due to space constraints, 63.5 mm in the lower section. The larger downpipe reduces backpressure, relieves the turbo, and allows for increased power output, depending on the components installed, up to 350 hp. To connect to the original exhaust system, a 63>54 mm reducer must be used, but typically larger exhaust systems are used during tuning.
