Milltek Sport OPF/GPF Delete Bypass Mid Pipes for BMW M5 F90/M5 Competition (2020+) S63 4.4 Twin Turbo V8 - T304 Stainless Steel Centre Section Straight Pipes - Fits OEM Downpipes & Stock Rear Exhaust - UK Made

Milltek GPF/OPF Bypass Pipes for BMW M5 F90 and M5 Competition 2020 onward

Turn up the character of your 4.4 twin turbo V8 with these Milltek Sport particulate filter bypass pipes. Purpose-built for the 2020+ BMW M5 F90 and M5 Competition, this centre section replacement links straight to the factory front pipes and the standard rear exhaust, giving you a freer-flowing, harder-hitting soundtrack and improved exhaust gas velocity.

Crafted in the UK from high quality T304 stainless steel, the Milltek centre pipes offer exceptional durability and a precise, bolt-on fit. Smooth-radius bends and quality welds help maintain consistent internal diameter for excellent flow and crisp throttle response. The result is a deeper, sharper note that lets the V8 breathe, while keeping the rest of the system OEM-compatible.

• Direct replacement for the particulate filter section on OPF/GPF-equipped M5 F90 models
• Mates to the original downpipes and the stock rear section on 2020+ cars
• UK-made T304 stainless for longevity and corrosion resistance
• Straight-through design to reduce back pressure and enhance V8 character
• Precise fitment with clean, high quality fabrication
