Ever since its launch in 2004, the BMW 1 Series has been a huge success. Many were adopted into the performance and tuning scene thanks to their excellent chassis, handling and powerful engines.
BMW are aiming to replicate the success of the previous model by launching two new performance variants on the F40 setup: the 128ti and M135i xDrive. For those wanting the most performance straight out of the box, the M135i xDrive fits the bill perfectly. However, for over £2,500 less, the 128ti does offer a tempting proposition for new car-buyers. Like the M135i, the 128ti features BMW's B48 2.0l turbocharged four-cylinder engine, but boasts a more modest 261bhp and 295 lb ft. These power figures bring it perfectly in line with the likes of VW's Golf GTI and Ford's Focus ST.
Unlike its big brother, the 128ti does not feature xDrive all-wheel drive, but for the first time in a performance BMW, features front-wheel drive. Whilst not as quick as its bigger brother, the 128ti is more involving and playful thanks to being lighter and front wheel drive.
More stringent European Emissions Standards mean the 128ti is shipped from the factory with a muted exhaust sound leading to a very disappointing driving experience. Cobra Sport were keen to awaken the sound and unlock the performance of the 128ti, and over the past few weeks, their research and development team have been hard at work developing an extensive range of performance exhaust systems including GPF backs and high flow front downpipes.
Cobra Sport opted for 3”/76.2mm precision TIG-welded T304 stainless steel pipework for the biggest upgrade in terms of performance, flow rate and sound levels.
For those who want to significantly improve sound levels, Cobra Sport offers their unique rear silencer delete setup. This performance exhaust is designed without a rear silencer to offer the biggest sound increase whilst keeping a sporty exhaust tone (+12.9dB in GPF back rear silencer delete configuration). This setup keeps the GPF filter in place enabling the car to pass a UK MOT test.
Cobra Sport have improved the styling of the BMW 128ti, creating a noticeably enhanced and balanced look to the rear of the car with a choice of dual 4” (101.6mm) and 4.5” (114.3mm) slash cut highly polished stainless-steel tailpipes. For those looking to take the style upgrade a stage further, upgraded carbon fibre tailpipes are available.
Like all Cobra Sport exhausts, this system utilises precision TIG-welding techniques for exemplary fit and finish – a feature that gives Cobra Sport an advantage over other manufacturers. With over 25 years in the performance exhaust industry, each Cobra Sport exhaust system is designed, manufactured and tested in Sheffield, the heart of the UK steel industry.
