Milltek Sport OPF/GPF-Back (Filter-Back) Exhaust System with Cerakote Black GT-100 Tips for BMW 5 Series M5 & M5 Competition F90 (4.4 Twin Turbo V8) 2020-on

Give your F90 the voice it deserves. This UK built filter-back system from Milltek transforms the soundtrack of the 4.4 litre twin-turbo V8 while keeping the factory gasoline particulate filters in place. Finished with stealthy Cerakote Black GT-100 quad tailpipes, it delivers a cleaner look and a richer, more purposeful tone that suits the M5 and M5 Competition perfectly.

Crafted from 304-grade stainless steel for long-term durability, the rear section features smooth, mandrel-formed tubing that reduces restriction and helps the engine breathe with less effort. Expect a deeper idle, a crisper rise in volume under load and refined cruising with no unwanted drone or cabin boom. It is the sweet spot for OPF equipped cars that want more character without compromise.

Highlights

• Filter-back layout that keeps the OE OPF GPF hardware intact on 2020-on cars
• Cerakote Black GT-100 100 mm quad tailpipes for a subtle, aggressive finish
• 304 stainless throughout for corrosion resistance and strength
• Precision bends for consistent gas velocity and a responsive feel
• Developed and manufactured in Britain by Milltek Sport
• Sporty tone on throttle, calm and comfortable on the motorway
