Fiesta ST 180 (MK7) Tubular Exhaust Manifold AIRTEC Motorsport

AIRTEC’s tubular exhaust manifold for the MK7 Fiesta ST 180 (1.6L EcoBoost, engine code D4FB) is built for flow, not fluff. No cast iron compromises. No vague ‘performance gains’. Just a properly engineered, TIG-welded, mandrel-bent manifold designed to support stage 2 fast road or track day builds - especially with hybrid turbo, decat downpipe or S55-style boost targets.

• Direct bolt-on for MK7 Fiesta ST 180 - no cutting, no welding, no ‘custom fitment’
• Optimised for EA888-derived tuning logic and N55/S55-style spool behaviour - yes, it works with stock ECU maps but shines with proper calibration
• Compatible with standard turbo (GT1544) and common hybrids (e.g. GT2052, GT2260), plus larger units where manifold backpressure matters
• Lighter and more thermally efficient than OEM - helps reduce under-bonnet heat soak on repeated track laps
• Fits with OEM downpipe flange (2.5” V-band or 3-bolt), so pairs cleanly with decat, catted or high-flow cats

Not for daily drivers chasing quiet refinement. Not for show cars needing OEM-plus aesthetics. This is for people who type ‘Fiesta ST 180 stage 2 manifold’ into Google at 2am - and want the part that actually delivers.
