Milltek Filter-back Exhaust for BMW 5 Series M5 & M5 Competition 4.4l Twin Turbo F90 (Non OPF/GPF Cars) (2018-2020) – Sharper Sound, Filter Retained
This is Milltek's particulate filter-back system for the BMW 5 Series M5 & M5 Competition 4.4l Twin Turbo F90 LCI (OPF/GPF Equipped Cars). It replaces everything downstream of the factory diesel or petrol particulate filter with wider-bore pipework and re-tuned silencers, cutting back pressure and sharpening the exhaust note. The filter itself is left exactly where the manufacturer fitted it, so emissions equipment is unaffected. It's offered in 5 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's the right choice if you want a sportier sound and a genuine, if modest, flow improvement on a filter-equipped car, without going anywhere near the parts of the system that keep it emissions-compliant.
