AIRTEC Motorsport De-Cat/Decat Downpipe for Ford Focus MK3 ST250 2.0 EcoBoost (2012-2018) Catless Turbo Downpipe | Track Use Only

AIRTEC Motorsport Race Down Pipe for Ford Focus ST 2.0 EcoBoost MK3 ST250

Transform the way your 2012 to 2018 Focus ST250 2.0T breathes with this AIRTEC Motorsport high-flow front pipe. It replaces the factory combined catalyst and front section with a straight-through, non-catted turbo outlet designed for track and competition use. By removing the most restrictive part of the front end exhaust, you unlock faster spool, crisper throttle response and a harder-hitting soundtrack once correctly mapped.

Performance benefits

• Free-flowing design reduces back pressure for improved turbo efficiency and stronger mid-range pull
• Quicker boost build and sharper throttle feel when paired with suitable ECU calibration
• More purposeful exhaust tone for motorsport environments
• Direct replacement with correct routing for the MK3 ST platform and sensor positions
• Ideal foundation for Stage 2 tuning, turbo-back systems and other supporting hardware

Compatibility

Fits Ford Focus ST MK3 ST250 2.0 EcoBoost - model years 2012, 2013, 2014, 2015, 2016, 2017 and 2018.

What to expect

• Noticeably freer revving character on circuit and fast road environments where permitted
• Enhanced turbo response and stronger in-gear acceleration when combined with a remap
• Pairs perfectly with a performance cat-back, induction kit and upgraded intercooler

Workshop feedback

We have installed this AIRTEC Motorsport front section on our own builds and for many MJ Modifications customers. The feedback is consistent - quicker spool, livelier mid-range and a more engaging exhaust note in a track environment.

Tuning and install notes

• ECU tuning is recommended to make the most of the hardware and manage emissions-related diagnostics
• As this removes the catalyst, an engine management light may appear without appropriate calibration
• Professional fitting is advised
