£177.45

AIRTEC Motorsport down pipe DE-cat for Ford Focus MK3 RS 2.3 Ecoboost.

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 uprated bore size of 70mm the new AS performance Replacement Down Pipe has over 50% more capacity meaning the exhaust gasses can exit the engine much quicker allowing for an increase in both power output and noise.

Custom Tuning is recommended to make the most of this product.

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.
