Cobra Sport Exhausts provide the exhaust solutions to the Motorbase Performance British Touring Car Championship team who for 2020 fielded??a trio of Mk4 Focus STs. This partnership allows us to test our products on track at the highest level of British Motorsport| the experience gained from the competitive track testing is fed??back into our road going exhaust system.??
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.
