DCE Parts - B58 Downpipe - F & G Chassis - BMW M140i, M240i, 340i, 440i, 540i, 640i, 740i & XDRIVE - (Slip On Clamp Type - Non-OPF)
The downpipe is 5.2 inch (132mm) measured at the biggest point including heat shield. The downpipe is 5.1 inch (129mm) excluding the heat shield
Through 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 up 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 B58 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 enhanced sound and a OE/Catted look. The DCE Parts Downpipe can also be fitted with a High-Flow Cat.
Note:
The Catless downpipes and Catless Catalytic Look Downpipes are only suitable for off-road use. The 200 Cell Sport Metallic Catalytic Converter Downpipes are suitable for road use in most Countries. We recommend to check your local law before purchasing the downpipes.

Seen on these builds
Fitment on this is perfect, everything went smoothly for a quick and painless install.
Bought the euro 6 300 cell with heat shield variant of this downpipe 6 months ago. Quality and fitment is very good. Exhaust note is about 25-30% louder with backbox valve open. With valve shut its much less. I bought the 300 cell so i could pass MOT with no problems. I had MOT done last month and a 4 gas test was not needed. OBD readiness for the two 02 sensors read as a pass on the scanner so a 4 gas test was not needed. Very nice. Overall im really happy with the downpipe. Recommended.
Good product, fits perfectly.
Nice people at the shop.
Very happy with the communication as well as with the quality of the downpipe. The fitment is perfect and the sound improvement is really good.
I highly recommend the company and their parts.
This downpipe really brought life to my 240i! I love it.
Fit and finish on the downpipe is spot on. Excellent product!

Emissions & road use
Catless, cat-delete and OPF/GPF-delete versions are intended for motorsport and off-road use only. Fitting them on a road-registered vehicle may not be permitted in your country and can affect type approval, inspections (MOT/APK/TÜV), warranty and insurance. Versions with a 200- or 300-cell high-flow catalytic converter keep a catalyst in place. Always check your local regulations before fitting. Catless and delete parts are not shipped to the United States.
