Scorpion Cat-Back Exhaust System - Ford Fiesta 1.0 EcoBoost (WZ) ST Valance - 63.5mm
This Scorpion cat-back exhaust replaces the factory system from the catalyst back on a Ford Fiesta 1.0 EcoBoost (WZ) fitted with the Fiesta ST rear valance. It is made from T304 stainless steel with 63.5mm (2.5") pipework and finishes in twin 83mm Daytona tailpipes. It is offered resonated or non-resonated, so you can pick a more refined tone or a louder, more aggressive one. Scorpion lists it as fitting to the factory front pipework or Scorpion's own front sections.

Scorpion exhaust system – Ford Fiesta 1.0 EcoBoost
Options – Resonance: the resonated version adds a resonator to take the edge off drone at highway speeds, while the non-resonated version uses straight pipe for a louder note. Tailpipe finish: "Daytona Polished Stainless" is the complete cat-back with twin Daytona tailpipes. "Standard" is not a complete system – it is Scorpion's rear silencer to cat-back upgrade kit (front/centre pipework only), which fits only to a Scorpion rear silencer (SFDB078ST or SFDB078ECO) already on the car.
Note: Requires the Fiesta ST rear valance (Ford parts 1813019 and 1866724). Australia received the 1.0 EcoBoost as the 92kW (125PS) Fiesta Sport (WZ, 2014–2015); the 100PS and 140PS versions Scorpion also lists were UK-only. The "Standard" option is an upgrade kit for an existing Scorpion rear silencer only. Installation by a professional is recommended.
Features
- 63.5mm (2.5") T304 stainless steel pipework
