Product description:
- The downpipe sits between the catalytic converter and 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 diameter of 63mm (original 54mm), an Interlook flex pipe, and brackets are installed. The larger downpipe reduces backpressure, relieves the turbo, and allows for more power, depending on the installed components, up to 330hp. The pipe is bent and is only welded at the flex piece and flange. To connect to the original exhaust system, a 63>54mm reducer sleeve must be used, but in most cases larger exhaust systems are used for tuning.
