Downpipe for Audi A4 A6 1.8T B5 3B 3BG Quattro ø 76mm 3" made of stainless steel

- Downpipe exhaust for Audi A4 A6 1.8T B5 3B 3BG Quattro ø 76mm 3" made of stainless steel

Description:

- the downpipe sits between the catalytic converter (Kat) and the exhaust system. It is bolted to the original cat, or you can use our plug&play 200 cells cat with the article number 340106. It has a diameter of 76mm (original 54mm), an interlock flex pipe, and mounts are installed. The larger downpipe reduces backpressure, relieves the turbo and allows for more power, depending on the installed components up to 400HP. The pipe is bent and only welded at the flex section and flange. To fit the original exhaust system, a reducing sleeve from 76>54mm is required, but usually, larger exhaust systems are used during tuning.

Suitable for:

and also for the following upgrade turbochargers:

- Borgwarner K04-015 53049880015

- Borgwarner K04-015 / K06

- Borgwarner K04-015 / TFSI Compressor Wheel
