Milltek Sport OPF/GPF-Back Resonated Performance Exhaust System for BMW M140i F20/F21 LCI 1 Series 2019+ (3 & 5 Door) - Carbon Fibre Jet-90 90mm Tips, T304 Stainless - Cat-Back/Axle-Back Rear Silencer Backbox Upgrade - B58 - OPF/GPF Models Only

Milltek rear section with resonator and carbon Jet90 tailpipes for BMW M140i F20/F21 LCI OPF 2019 onwards

Give your BMW M140i the soundtrack it deserves. This Milltek Sport rear system replaces everything from the particulate filter backwards on OPF/GPF-equipped facelift models, adding a deeper, richer tone and a premium motorsport look with stunning carbon fibre 90 mm tailpipe finishers. It is the ideal sound and style upgrade for the F20 and F21 1 Series hot hatch without unwanted cabin boom.

Built in Britain from T304 stainless steel, the pipework is mandrel bent for smooth flow and durability in all weather. The silenced centre section keeps motorway manners refined while letting the B58 straight six sing when you press on. Fitment is straightforward using factory mounting points and the overall quality is exactly what you expect from Milltek.
