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 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. The difference in sound is illustrated in the sound video on our product page - BMW M140i PPF / GPF Delete Exhaust.
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.
