Milltek Sport Rear/ Cat-Back/Catback/Axle-Back Exhaust for BMW M5 F90 (2020+) & M5 Competition | OPF/GPF Delete Bypass Pipes | Cerakote Black GT-100 100mm Tips | 4.4 Twin-Turbo V8 Performance Sports Exhaust | Stage 2 ECU Required | UK 304 Stainless

BMW F90 M5 Exhaust System Upgrade by Milltek Sport with particulate filter bypass and GT-100 black ceramic tips

Give your F90 the sound and presence it deserves. This Milltek Sport rear section system replaces the factory pipework and introduces a free flowing layout with a gasoline particulate filter bypass, unlocking a harder edged tone and faster breathing from the 4.4 litre twin turbo V8. Finished with stealthy Cerakote black GT-100 tailpipes, it delivers a purposeful motorsport look to match the performance.

Crafted in the UK from premium 304 grade stainless steel, the tubing uses smooth radius bends and enlarged diameter sections to reduce back pressure and support tuned applications. Acoustic development focuses on a deep, clean soundtrack that comes alive under load while remaining civilised on the motorway. Built to last, built to perform, and built to transform the driving experience.
