Materials and build

Every Milltek system is designed, developed and hand-finished in the UK. Type 304 non-magnetic stainless steel resists discolouration and offers outstanding longevity. Mandrel bending maintains a constant radius for superior gas flow. Bore diameters are enlarged over stock in the right places to release performance without hurting response or mid-range torque. The result is a crisp, sporty soundtrack that stays civil on the motorway and avoids unwanted drone.

Professional installation recommended. Once the correct 435i M Sport rear valance is installed, this system is a straightforward bolt-on cat-back upgrade. For fitting, we can help. Nforcd is based in Warwickshire and offers a fitting service. Request a quote at Sales@nforcd.com.
