Description
Installing a Downpipe for your BMW N20 will provide great performance and is the best bang for buck modification. Purchase your N20 downpipe for more performance.
DCE Parts - N20 N28 Downpipe - N20 120i 228i 320i 328i 428i F20 F21 F22 F30 F32 F33 F36 2013-2016
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 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.

QUESTIONS BEFORE YOU BUY
Still in doubt? We answer on WhatsApp during workshop hours.
Do I need a remap?
Yes. For proper operation and optimal power output, the ECU needs a remap to accommodate the downpipe, especially the catless version.
Is this downpipe road legal?
The Catless and Catless Catalytic Look versions are for off-road use only. The 200 Cell Sport Metallic Catalytic Converter version is suitable for road use in most countries. Please check your local law before purchasing.
How much power does it add?
A larger downpipe lowers back pressure, so the turbo spools up quicker and rebuilds pressure faster after gear changes. The downpipe alone usually adds about 15 HP and 25 Nm, and it improves the sound of your car.
Will it fit my car?
This downpipe only fits cars with OPF and the V-Band flange type. Check the outlet type of your OEM downpipe. The difference is usually an OPF filter or no OPF filter. Contact us if you are unsure.
Which OEM numbers does it replace?
18329488919 and 18329489938.

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.
