The AIRTEC Decat Downpipe allows exhaust gases to flow much faster, which results to increased power gains.

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

Features:

  • Made from stainless steel
  • AIRTEC laser cut plaque
  • Smooth bends to ensure increased flow
  • Cast elbows to retain diameter
  • Fits original and aftermarket exhaust systems
  • Improved performance further enhanced with remap

Will fit the following models:

  • F20/F21 – 140i
  • F22/F23 – 240i
  • F30/F31 – 340i
  • F32/F33/F36 – 440i
  • G30/G31/G38 – 540i
  • G32 GT 640i
  • G12 740i
  • G01 X3 M40i
  • G02 X4 M40i
