AIRTEC Motorsport De-Cat Downpipe for BMW S63B44TU engine (M5/M6)
By removing the original restrictive catalytic converter in the OEM factory downpipe, back pressure is hugely reduced, resulting in faster spool, increased power, and a much more aggressive exhaust note.
Features:
- Made from stainless steel
- AIRTEC laser cut plaque
- Smooth bends to ensure increased flow
- Fits original and aftermarket exhaust systems
- Improved performance further enhanced with remap
Will fit the following models:
- F10 M5
- F06/F12/F13 M6
Please note: De-cats are sold for motorsport and off-road use only and will not pass a UK MOT test or police roadside checks.
AIRTEC Part No: ATEXHBMW2
