Cobra Sport / M140i (F20 / F21 LCI) 3 & 5 Door (2015-19)
BMW M140i De-Cat / Sports Cat Downpipe Performance Exhaust
Part Number: BM85
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 downpipe fits from the turbo to the centre exhaust to replace the standard catalyst.
The high flow sports catalyst option includes a 4.5in/114.3mm 200 cell high flow sports catalyst matched with 4.5"/114.3mm reducing to 3"/76.2mm pipework. The de-cat option is manufactured utilising 3.5"/88.9mm pipework.
The de-cat exhaust version is sold for motorsport and off road use only worldwide.
The sports catalyst version replaces a factory emissions device and is not EC homologated. This may not meet current emission laws for road use in your territory.
All relevant fittings and gaskets are supplied.
The product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product.
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
Cobra Sport accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customers responsibility to ensure that all local laws are adhered to within their home state/country.
Designed and manufactured to uncompromising standard, Cobra Sport has matched performance improvements with re-defined sound to offer an exciting exhaust upgrade offering for M140i owners.
The Cobra Sport research and development team quickly made the decision to base the new performance cat back exhaust systems for the BMW M140i 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 M140i 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.
Testing of the standard M140i revealed power figures of 327 whp and 367 lbft. Working in conjunction with one of our tuning partners AET Motorsport, we installed the Cobra Sport turbo back system (with de-cat) on the AET Motorsport development car and ran further power testing. With the Cobra Exhaust installed, the M140i recorded 349.2 whp and 389.9 lb-ft, an increase of 22 whp and 23 lb-ft with a fantastic sound track to match. Taking this one step further, AET installed Burger Motorsport JB4 and the EWG loom and ran dyno power runs on map 1,2 and 5. The best results were seen to be on Map 5 where the BMW M140i produced 423 whp and 453 lb-ft this means an overall increase of 96 whp and 86 lb-ft over the stock vehicle.
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 M140i. 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 M140i, 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.
