Press Release

Cobra Sport are pleased to announce the launch of their performance exhaust systems for the BMW M135i (F20/F21) 3 & 5 Door. Designed and manufactured to uncompromising standard, Cobra Sport have matched performance improvements with re-defined sound to offer an exciting package for M135i owners.

The Cobra Sport research and development team quickly made the decision to base the new performance exhaust systems for the BMW M135i on 3′ (76.2mm) T304 stainless steel pipework. This pipework allows the engine to breathe and contributes to our aim for the largest natural performance improvements. Independent testing of the non resonated cat back system revealed impressive gains of +10bhp along with 16 lb ft of torque. The outstanding power results are complemented by a significant weight advantage with the Cobra Sport system weighing only 16.32kg giving a 20% decrease from the OEM weight of 20.38kg.

Cobra Sport Sales Manager Matt Thomas commented ‘We’re very excited about the release of the system for the M135i. The 3.0 litre engine has a fantastic reputation and our Research and Development team have been able to extract excellent power gains. The pick of the systems is the non resonated cat back exhaust, the sound is incredible with a beautiful pitch and tone. The sound from this system brought a local street to a standstill when out testing so I anticipate the systems to be a great success’.

The new systems for the M135i 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 in the form of either a sports cat or a de-cat pipe to create the most dynamic sound track.

The BMW M135i has an aggressive stance on the road with wide flared wheel arches matched with a smart but subtle body kit. Cobra Sport have managed to improve the styling over the standard M-sport exhaust by finishing off the rear of the M135i with a more aggressive and balanced look by finishing the system with a choice of dual 3.5′ (88.9mm) inward rolled baffled or inverted highly polished stainless steel tailpipes.
