BMW M140i Resonator GPF/PPF Delete Performance Exhaust

Fits both PPF and earlier pre-PPF models - requires mandatory ECU reflash when fitted to PPF models. Fitment to PPF equipped models is for motorsport and off road use only.

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 BMW M140i performance exhaust is made in 3inch/76.2mm pipework and fits from the catalytic converter section to before the rear box replacing the whole centre section.

This exhaust makes the system louder as it removes the standard resonator or PPF filter on later models and both resonators on earlier models and therefore, offers a significantly sportier exhaust note.

All relevant fittings and gaskets are supplied for fitment and to revert back to the standard exhaust.

Fitment to later M140i models which have the PPF filter as standard will require basic engine tuning at time of fitment to cancel the EML light.

Fitment is for motorsport and off road use only as it removes the PPF filter. 

Press Release

With its potent, 335bhp turbocharged engine and an engaging chassis, the latest BMW M140i delivers a thrilling driving experience, all wrapped up in a stylish and solidly built package. However, there's always room for a little improvement.

As with all new models, the M140i is fitted with a PPF (petrol particulate filter), which limits the potential of that fantastic 3.0-litre straight six 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) mandrel-bent pipe features TIG-welded hangers and removes a significant restriction in the exhaust system.

The main brief was to improve the sound and unleash the full potential of that straight-six engine. Following intensive development, Cobra Sport have delivered a product that truly awakens the sound of the M140i, while also improving gas flow.

The exhaust now emits a deep and vibrant tone, especially evident under load, while under deceleration, there's now an audible burble, accompanied by pops and bangs. This simple, but effective upgrade completely changes the character of the car, giving it a more sporty and thrilling sound with a 7.5% dB increase.

A direct replacement for the OEM part, the Cobra Sport PPF Delete is the most cost-effective way to improve the sound of the stock M140i. A simple ECU reflash will be required at the time of fitting to prevent engine warning lights illuminating.

A Centre Resonator Delete Pipe is also available for earlier, pre-PPF M140is, which delivers similar improvements, but without the need for an ECU reflash.

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.
