Description
DCE Parts – BMW N63TU / N63N 550i / 650i / X5 X6 50i Downpipes With Heat Shield
The DCE Parts Downpipes for the BMW N63TU V8, also identified as N63N in BMW parts catalogues, are available in a Catless Heat Shield version or with High Flow 200 Cell Catalytic Converters and Heat Shield. Supplied as a pair, these downpipes replace the factory catalytic converter assemblies for both cylinder banks.
This version is intended for the N63TU exhaust configuration with integrated outlet bends and lower clamp connections. It is different from the original N63 version with bolted lower flanges and separate connecting pipes.
A less restrictive downpipe configuration can reduce exhaust back pressure and give the N63TU V8 a more pronounced exhaust sound. Changes in turbo response and power depend on the vehicle, the selected version and ECU calibration. No fixed power increase is specified.
The heat shielding helps limit radiant heat around the downpipes. Professional installation is recommended, including checking the exhaust connections, sensor positions and surrounding clearances.
Available versions:
-
Catless Heat Shield: downpipe pair without catalytic converters, with heat shielding.
-
High Flow Cat 200 Cell With Heat Shield: downpipe pair with 200 cell high-flow catalytic converters and heat shielding.
BMW applications — N63TU / N63N configuration only:
-
BMW F07 550i / 550i xDrive Gran Turismo with the N63TU engine.
-
BMW F10 / F11 550i / 550i xDrive with the N63TU engine. For the F10, generally production from July 2013, with European factory output of 450 hp / 330 kW.

Production changeovers differ between models. The F10 changeover date must not be applied to the entire model range. Compatibility must be checked using the VIN and original exhaust configuration.
BMW OE reference numbers:
| Cylinder bank | OE reference |
|---|---|
| Cylinders 1–4 | 18327645440 |
| Cylinders 5–8 | 18327645441 |
OE numbers are provided for identification and fitment comparison. Vehicles with different OE numbers require an individual compatibility check.
Fitment verification:
Please provide your VIN, production date and photographs of the original downpipe connections before ordering if compatibility is uncertain. The N63 designation alone does not confirm fitment.
Not suitable for the original N63 lower flange connection type or G30 M550i / M850i N63R and OPF applications.
Please note:
These products are intended for off-road or motorsport use. No vehicle-specific road-use approval is supplied. A 200 cell catalytic converter does not by itself establish road-use approval.
ECU calibration requirements and the possibility of a check-engine light depend on the vehicle and selected version. Fault-free operation without software changes is not guaranteed.
Please send us your VIN when in doubt.

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.
