Focus RS MK3 (2016-2018) AIRTEC Motorsport 70mm Catless Downpipe, Part No. DP-FRS3-CATLESS

This is the AIRTEC Motorsport 70mm catless downpipe for the Focus RS MK3 - no fluff, no filler, just a bolt-on decat for fast road, track day or stage 2 builds. It replaces the restrictive OEM one-piece unit (55 mm bore, tight bends) with a true 70 mm flow path and smooth mandrel bends.

• Designed specifically for the Focus RS MK3 (2016-2018), EA888-based 2.3L EcoBoost engine
• True catless construction - no catalyst, no compromise on flow; intended for off-road, track day or show car use only
• Compatible with stage 1 maps out of the box; essential for stage 2 (larger turbo, intercooler, intake)
• No ECU remap required for improved throttle response - though a tune is mandatory to run safely long-term
