09 Design GPF-Back Exhaust System – Ford Fiesta ST Mk8/8.5 (Pre-Sep 2020, 3-bolt actuator)
The 09 Design GPF-back exhaust unlocks a sharper sound and smoother flow for your Fiesta ST Mk8/8.5. It replaces the pipework after the GPF, so factory emissions hardware stays in place.
Built from 304 stainless steel with a 60 mm bore, it reduces back-pressure for crisper throttle response. The internal mufflers are tuned to avoid cabin boom in daily driving. Switch drive modes and the tone deepens with authentic pops and bangs when you want it.
Every system is precision welded for an exact fit. It features an embossed rear resonator, 09D carbon fibre tailpipe trims and a premium matt finish.
- Important: For cars with the 3-bolt exhaust valve actuator used on pre-September 2020 models.
- Retains factory valve control and all emissions components.
- Direct fit to OEM mounting points.
