Cobra Sport BMW M135 F70 Quad Exit GPF-Back Exhaust System
Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience, while being fully guaranteed for assurance of our quality.
This BMW M135 (F70) performance exhaust is made with a combination of 3" (76.2mm) and 2.5" (63.5mm) pipework and fit from the Gasoline Particulate Filter section backwards (GPF-back). Offering improvement in terms of exhaust tone, bass and sound level, replacing the centre and rear sections whilst keeping the stock catalyst and GPF in place.
Featuring a single sleek look resonator to accentuate the factory valve functionality, transforming this ordinarily timid sounding M Sport model. With a selection of 4" (101.6mm) tailpipe options including a choice of carbon fibre tips.

All relevant fittings and gaskets are supplied.
