AIRTEC MOTORSPORT – DOWNPIPE DE CAT FOCUS MK3 ST250

Description

AIRTEC Motorsport downpipe decatalyst for Focus MK3 ST250

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 70 mm.

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.
