Designed and manufactured to uncompromising standard, Cobra Sport has matched performance improvements with re-defined sound to offer an exciting exhaust upgrade offering for M240i owners.

The Cobra Sport research and development team quickly made the decision to base the new performance cat back exhaust systems for the BMW M240i on 3" (76.2mm) T304 stainless steel pipework. This mandrel bent pipework allows the engine to breathe and contributes to the aim for the largest natural performance improvements. The new cat back exhausts offer a significant weight advantage with the Cobra Sport system weighing only 16.32kg giving a 21% decrease from the OEM weight of 20.75kg. The sound of the new Cobra Sport exhausts boast vastly improved tonal characteristics with the non resonated cat back exhaust offering a deeper more aggressive sound with an overall increase of +4.6dB to 86.8dB on the static 4,000rpm sound test. Within the cabin the redefined sound remains comfortable registering 81.6dB under full load.

The new systems for the M240i are based around a cat back configuration with the option for either a resonated or louder non resonated centre section. These cat back systems can be matched with a choice of replacement front pipe options in the form of either a sports cat or a de-cat pipe to create the most dynamic sound track and performance potential.

Cobra Sport Sales Manager Matt Thomas commented "Building on an existing first class reputation in the BMW tuning market, we're excited to be adding the Cobra Sport sound and performance upgrade to the stunning M240i. Through optimised gas flow technology, the downpipes have been designed for fitment in conjunction with engine tuning requirements with our tuning partners reporting exceptional power gains, all made possible by the Cobra Sport exhaust upgrade."

Cobra Sport have improved the subtle styling of the BMW M240i, creating a more aggressive and balanced look to the rear of the car with a choice of dual 3.5" (88.9mm) inward rolled baffled or inverted highly polished stainless steel tailpipes.
