Cobra Sport 3" Valved Turbo Back Exhaust (De-Cat) - BMW F80 M3 | F82 M4

This Cobra Sport turbo back system replaces everything from the turbos rearwards on the F80 M3 and F82 M4 - front pipes, factory catalysts, centre and rear sections - with 3" (76.2mm) T304 stainless steel pipework. A centre H-pipe balances flow from both banks for a deeper, more aggressive note under load, while the retained exhaust valves keep the drive-mode sound control you get from the factory.

Please note: Suitable for pre-GPF/PPF models only. Includes primary and secondary de-cat sections, so it is sold for motorsport / off-road use only. Removing the primary catalyst will trigger the EML light - an ECU remap is recommended to correct this and to make the most of the extra flow. Requires 2 x genuine BMW gaskets (part number 18307851168), which are not included. All other gaskets and fittings are supplied.
