Ford Fiesta (Mk8) (2018-22) ST Cat Back Valved Performance Exhaust

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 Catalyst section backwards (Cat-back) replacing the 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.

Please note: this exhaust removes the GPF filter and will require basic engine tuning at time of fitment to cancel the EML light.

Fitment to GPF equipped models is for motorsport and off road use only.

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.

Cobra Sport Exhausts provide the performance exhaust solutions for the Mk4 Focus STs raced by the MB Motorsport accelerated by Blue Square and Motorbase Performance teams in the 2021 Kwik Fit British Touring Car Championship. This technical partnership allows us to test our products on track at the highest level of British Motorsport. The experience gained from the competitive track environment is fed back into all of our road going performance exhaust systems.

The bore size of the Cobra Sport exhaust has been increased to 3" (76.2mm), which is unique in the market providing the greatest upgrade in terms of performance, flow rate and sound levels.

In order to keep the use of the drive select modes, the Cobra Sport exhaust range has been designed with the inclusion of the active valve to help regulate exhaust tone at low speeds and keep the tone differences between drive modes.

The Cobra Sport Mk8 Fiesta ST exhausts are finished with twin 3.5" highly polished stainless steel or ceramic black slash cut tailpipes engraved with the Cobra Sport logo along with a 3.5" Carbon Fibre tip option.

As with all Cobra exhaust developments, power increases, sound improvements and manufacturing quality are top of the priority list during development. Superior TIG welding techniques during the manufacturing process set the Cobra Sport exhausts apart from the competition. The levels of quality achieved enables us to offer a lifetime guarantee on all exhaust systems which provides the ultimate peace of mind for the customer.
