Milltek BMW F90 M5 Pre LCI OPF Delete Mid Section absolutely transforms the sound of the M5's 4.4l twin-turbo V8. This mid-section bypasses the factory OPF's and is a really cost-effective way of improving your vehicle's exhaust sound. 

Milltek Sport exhausts are produced in high quality type 304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers' stainless steel may not be) and is less susceptible to discolouration. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek Sport exhaust systems are increased in bore to ensure ultimate performance without the loss of mid-range torque. All Milltek Sport exhausts are designed, developed and manufactured in-house in the UK.

Please note: You will need OPF delete cables or a stage 2 tune to run this mod-section.

*Only fits vehicles equipped with OPF filters.
