The ST is the sports-oriented line, aimed at select vehicles produced by Ford. Performance can be enhanced with a combination of Milltek parts, including this Downpipe and De-Cat. Milltek Sport Large-Bore Downpipes are designed to improve both performance and sound. These downpipes feature a larger diameter than standard OEM parts, allowing significantly more gas to exit the engine and pass through, which increases efficiency. As this is the De-Cat version, it offers significant power gains without the restriction on gas flow caused by a catalyst. - Large-bore design increases exhaust gas flow - De-Cat version eliminates catalyst restriction - Designed for improved performance and sound - Fabricated for select Ford ST models Specifications: - Pipe Diameter: 80.00 mm - Installation Time: 2 to 2.5 hours (including removal of OE system) - Race Product: Yes - EMarked: No Kit comes with: - 80mm Decat Downpipe - MSFD270REP Vehicle Compatibility: - 2020 and later Ford Fiesta Mk8 & Mk8.5 ST 1.5 EcoBoost 200PS (Post Sept 2020 Models Only) - 2018-2020 Ford Fiesta Mk8 ST 1.5 EcoBoost 200PS (Pre Sept 2020 Models Only) - 2020 and later Ford Puma ST 1.5 200ps EcoBoost (OPF/GPF Equipped)
