AIRTEC Motorsport De-Cat Downpipe for Focus RS Mk3
Upgrade your Mk3 Focus RS with the AIRTEC Motorsport de-cat downpipe and unlock serious exhaust flow. The factory Focus RS Mk3 catalyst and downpipe are a single one-piece item with restrictive bends and a small 55 mm exit bore. This AIRTEC Motorsport replacement de-cat downpipe increases the bore to 70 mm, offering over 50 percent more capacity for reduced back pressure and improved gas velocity. The result is a harder-hitting, more responsive Focus RS Mk3 that sounds and feels the way a performance Ford should.
We have fitted and used this AIRTEC Motorsport downpipe on our own builds and customer cars, and the feedback has been consistently positive. Expect faster spool feel, sharper throttle response and a more aggressive exhaust note under load. If you are building a track, time attack or off road Focus RS Mk3, this is a must-have exhaust upgrade.
