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 128ti performance exhaust is made in 3″/76.2mm pipework and fits from the Gasoline Particulate Filter section backwards (GPF-back) replacing the centre and rear sections. GPF Back with Box Delete Test Results: Sound – Engine at Idle: 70dB (+12.7dB) – Static 4,000rpm test: 91dB (+8.5dB) All relevant fittings and gaskets are supplied. Please Note: The ‘Valved’ exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will continue to swap from quieter to louder tones as before. The ‘Non-Valved’ exhaust removes the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however, the Cobra Sport exhaust has been designed with this in mind.
