Available Now - BMW M135i Performance Exhaust Systems

The BMW M135i has been described as one of the purest, most enjoyable driving BMWs to have been released in a very long time. The M135i boasts a turbocharged 3.0-litre straight-six engine matched with rear wheel drive, making it a very attractive offering with exceptional handling characteristics and acceleration to match.

The 3.0 litre engine found in the M135i gives an impressive 0-62mph time of just over 5 seconds. Our development model benchmarked 306bhp and 290 lb-ft when tested on the rolling road.

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 R&D 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 it to be a great success".

The new sports exhaust systems are available in a number of configurations to cover the many different needs of M135i owners. The systems 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 front pipe replacement with either a sports cat option to further increase the available power gains along with 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 are keen to improve the styling over the standard M-sport exhaust to finish off the rear of the M135i with a more aggressive and balanced look by finishing the system with 3.5" (88.9mm) inward rolled baffled highly polished stainless steel tailpipes.
