Unlock the Fiesta ST Mk8.5 soundtrack and response with a premium turbo downpipe upgrade available with a high-flow sports catalyst or catless option. Crafted in free-flowing 76.2 mm 3 inch stainless steel from the turbo housing to the GPF OPF join, this front section transforms throttle response and unleashes a richer, more aggressive tone while keeping drone in check. Ideal for enthusiasts seeking a sharper driving feel on the road or on track.
Why upgrade this turbo downpipe
- 3 inch 76 mm large-bore pipework for reduced back pressure and faster turbo spool
- Precision stainless construction for durability and a quality finish
- Direct-fit from turbo outlet to the factory GPF OPF connection
- Choose between high-flow sports cat or straight-through decat pipe
- Supplied with the required hardware and gaskets for installation
Fitment and compatibility
Designed for the Ford Fiesta ST Mk8.5 1.5 EcoBoost facelift model. Fits the front section from the turbocharger to the centre GPF OPF assembly, replacing the factory front pipe.
Options explained
- Sports catalyst High-flow catalytic converter to increase gas velocity and performance potential compared with the OE unit. This replaces factory emissions equipment and is not EC homologated. It may not meet current road-legal emissions requirements in your region.
- Decat downpipe Catless front section for maximum flow. Sold for motorsport and off-road use only worldwide.
Tuning and EML note
Due to the increased flow rates, engine calibration is recommended at the time of installation to avoid an EML light and to optimise drivability and performance.
