Milltek Sport BMW M5/M5 Competition LCI Cat Back Exhaust System (F90)

Milltek BMW F90 M5 LCI Full Cat Back Exhaust System absolutely transforms the sound of the M5’s 4.4l twin-turbo V8. The full system runs from the factory catalytic convertors all the way to the tips, bypassing the factory OPF. The Milltek system is therefore far more free-flowing for improved performance and increased tuning potential.

The Milltek Catback System retains the OEM valve functionality, making it great to live with on a daily basis.

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 system.

*Only fits vehicles equipped with OPF filters.
