AIRTEC Motorsport 70mm Decat (De-Cat) Downpipe/Front Pipe for Ford Focus RS Mk3 2.3 EcoBoost (2016-2018) | Cat Delete/Catless Test Pipe, Straight-Through Turbo Outlet | Performance Exhaust Upgrade | Track/Off-Road Only | Race Front Section

AIRTEC Motorsport 70 mm Cat Delete Front Pipe for Focus RS Mk3 2.3 EcoBoost

Free the exhaust on your 2016 to 2018 Focus RS Mk3 with this race front section from AIRTEC Motorsport. The factory combined catalyst and front pipe is a single-piece item with tight-radius bends and an approximately 55 mm outlet. AIRTEC’s replacement increases the bore to 70 mm, giving more than 50 percent additional cross-sectional capacity to cut backpressure and improve gas speed. The result is a sharper, stronger-feeling RS that delivers faster turbo response and a more purposeful soundtrack on track.

We have installed this unit on our own cars and many customer builds, and feedback has been consistently excellent. Expect quicker spool characteristics, crisper throttle response and a more assertive tone under load. If you are building a circuit, time attack or off-road-focused Mk3, this is a key exhaust front section upgrade.

Key advantages
