Ford Focus ST (Mk4) GPF / PPF Delete 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 Focus ST Mk4 performance exhaust is made in 3"/76.2mm pipework and fits from the downpipe to the centre section, replacing the GPF exhaust section.

This exhaust makes the system louder as it removes the GPF filter and therefore, offers a significantly sportier exhaust note.

All relevant fittings and gaskets are supplied for fitment.

Fitment will require basic engine tuning at time of fitment to cancel the EML light.

Fitment is for motorsport and off road use only.

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.

Press Release

As with all new models, the Mk4 ST 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. 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.
