DCE Parts -  BMW S58 X3M X4M F97 F98 Catless / Catlook / High Flow Cat Downpipe

The DCE Parts Downpipe for the S58 X3M and X4M can be specced with a Catalytic Converter Look (note: no functional Catalytic Converter), full Catless or with High Flow Catalytic Converters.

With the placement of a bigger 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 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.

DCE Parts introduced a line up of Downpipes that not only offer more performance, but also much nicer sound. The DCE Parts Downpipes are optionally specced with a Catalytic Look while being catless, for enhance sound and a OE/Catted look. The DCE Parts Downpipe can also be fitted with a High-Flow Cat.
