Description:
- The Y-pipe sits between the catalytic converter and the exhaust system. It is screwed to the original catalytic converter or our plug&play 200 cell catalytic converter with the item no. 340106 can be used. It has a cross-section of 63mm (original 54mm), an Interlook flex pipe and holder are installed. The larger downpipe reduces the back pressure, relieves the turbo and allows more power to be delivered, depending on the installed components up to 330HP. The pipe is bent and only welded at the flex piece and flange. To match the original exhaust system, a reduction sleeve from 63>54mm must be used, but usually larger exhaust systems are used during tuning.
