AIRTEC Motorsport Downpipes for BMW S63 engine (M5/M6)

Technical Data

AIRTEC Motorsport De-Cat Downpipes for BMW S63B44TU engine (M5/M6)

By removing the original restrictive catalytic converters located within the factory OEM downpipes, back pressure is hugely reduced, which in return means faster response, increased power and a more aggressive exhaust note.

One of the only manufacturers that offer a cast elbow to retain diameter!

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 road side checks.
