Downpipe for Audi A4 B7 2.0 TFSI Quattro ø 63.5mm after catalytic converter

- Downpipe / Downpipe for Audi A4 B7 2.0 TFSI Quattro ø 63.5mm from cat

Description:

- the downpipe is located between the catalytic converter and exhaust system. It is bolted to the original cat. It has a cross-section of 63.5mm. By using a larger downpipe, the back pressure is reduced, the turbo is relieved, and more power can be achieved, depending on the installed components up to 350HP. To adapt to the original exhaust system, a reducer sleeve of 63>54mm must be used, but in tuning, larger exhaust systems are mostly used and then the pipe cross-section should not be reduced.

Suitable for:

- Audi A4 B7 2.0 TFSI Quattro

Optional parts:

- matching 200 cells sports catalytic converter 340111
