Description:
- the downpipe is located between the catalytic converter and the exhaust system. It is bolted to the original catalytic converter or our plug&play 200 cell catalytic converter with item no. 340106 can be used. It has a cross-section of 63mm (original 54mm), an Interlook flex pipe and bracket are installed. The larger downpipe reduces back pressure, relieves the turbo and allows more power to be run, up to 330PS depending on the installed components. The pipe is bent and welded only at the flex section and flange. To connect to the original exhaust system, a reducer sleeve from 63.5>54mm must be used, but largerexhaust systems are mostly used for tuning.
