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 Focus Mk4 ST turbo back performance exhaust is made in 3"/76.2mm pipework and fits from the Turbo backwards (turbo-back) replacing the Downpipe, GPF, centre and rear sections.
The non-resonated option makes the system louder as it excludes the centre silencer and therefore, has a sportier exhaust note. This exhaust however, is also available as a resonated version (including centre silencer) which is a quieter option.
The de-cat exhaust version is sold for motorsport and off road use only worldwide.
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.
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 product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product.
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
Cobra Sport accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customers responsibility to ensure that all local laws are adhered to within their home state/country.
