Cobra Sport Cobra Exhausts - Ford Focus ST (Mk4) Turbo Back Performance Exhaust
Requires mandatory ECU reflash. 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.

Press Release As with all new models, the Mk4 ST Estate is fitted with a GPF (petrol particulate filter), which limits the potential of the engine, leading to a muted and slightly disappointing sound. Cobra Sport's engineers have developed a solution in the form of their new PPF Delete. This high-quality, 3in (76.2mm) TIG welded stainless steel performance exhaust removes a significant restriction in the exhaust system. A direct replacement for the OEM part, the Cobra Sport GPF Delete is the most cost-effective way to improve the sound of the stock Mk4 ST Estate. A simple ECU reflash will be required at the time of fitting to prevent engine warning lights illuminating. Like all Cobra Sport exhausts, this product utilises precision TIG-welding techniques for exemplary fit and finish a feature that sets Cobra Sport apart from other manufacturers.

Press Release The Ford Focus ST has long been a favourite amongst hot hatch fans, especially in the UK, ever since the launch of the Mk1 ST170 back in 2002.
