Scope of delivery:- Downpipe for Audi A4 A6 1.8T B6 Quattro, ø 63.5 mm (2.5"), made of stainless steel with Interlock flexible hose

Description:
- The downpipe is located between the catalytic converter and the exhaust system. It is bolted to the original catalytic converter, or our plug-and-play 200-CPI catalytic converter (item no.340106 ) can be used. It has a cross-sectional diameter of 63.5 mm (original: 54 mm) and features an Interlook flexible pipe. The larger downpipe reduces back pressure, relieves the turbo, and allows for increased power output—up to 450 PS, depending on the components installed. The pipe is bent and welded only at the flexible joint and flange. To connect to the original exhaust system, you’ll need to use a 76-to-55-mm reducer sleeve, but in most cases,larger exhaust systems are used for tuning.
