Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.

This Ford Fiesta Mk8 ST cat back performance exhaust are made in 3"/76.2mm pipework and fit from the turbo section backwards (turbo-back) replacing the downpipe, GPF, centre and rear sections.

Please Note - This performance exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will continue to swop from quieter to louder tones as before.

All relevant fittings and gaskets are supplied. 

Note: This performance exhaust fits all Mk8 Fiesta ST model years as it includes the valve motor allowing easy plug and play connectivity without the need to remove and reuse the existing valve motor.

The sport catalyst version replaces factory emissions devices and is not EC homologated. This may not meet current emission laws for road use in your territory.

Fitment is for motorsport and off road use only as it removes the PPF filter. 

IMPORTANT: This exhaust removes the PPF (Petrol Particulate Filter) and will require engine tuning at time of fitment to cancel the EML light on PPF equipped vehicles.

Fitment is for motorsport and off road use only as this system removes the GPF filter.
