Through the placement of a bigger B58 Downpipe the turbo spools up quicker due to a lower back pressure. The turbo starts to build up pressure at lower speeds. It also manages to build it pressure quicker after gear changes. The installation of the B58 Downpipe alone usually provides 15 HP and 25Nm extra. By installing the downpipe, you will enhance the sound of your vehicle as well.
For proper operation and optimal power output, the vehicle will need remapping of the ECU to accommodate the catless downpipe. This product is not suitable for road use.
Options
Most DCE Parts Downpipes can be specced with a full straight Decat, a Catalytic Converter Look (but with empty cat) or with a High Flow Cat.
