AIRTEC Motorsport downpipe de-cat for Focus MK3 RS


The Original Catalyst and down pipe , unlike the older ST225 and Focus RS mk2, are made in one piece. This new design features some restrictive bends and an exit bore size of only 55mm.


With a new bore size of 70mm the new AS performance Replacement Down Pipe has over 50% more capacity.


This part is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks. This part however, is also available as a high flow sports catalyst version, which will pass these checks.
