AIRTEC MOTORSPORT – DE CAT DOWNPIPE FOCUS MK3 RS

Description

AIRTEC Motorsport downpipe decat for Focus MK3 RS

The original catalytic converter and exhaust pipe, unlike the old ST225 and Focus RS mk2, are made in one piece. This new design features some restrictive curves and an exit hole size of only 55mm.

With a new 70mm hole, the new AS performance replacement downtube has more than 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 roadside checks. This part, however, is also available in a high-flow sports catalyst version, which will pass these checks.
