Milltek Cat-back Exhaust for BMW 5 Series M5 Saloon M TwinPower Turbo V8 (F10) (2011-2016) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the BMW 5 Series M5 Saloon M TwinPower Turbo V8 (F10). It replaces everything from the factory catalytic converter rearward with wider-bore pipework, a re-profiled mid-pipe and silencers tuned specifically for this platform, cutting back pressure and sharpening the exhaust note. The factory catalytic converter stays in place, so the car's emissions hardware is left as standard. It's offered in 3 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's aimed at owners who want a noticeably different sound and a genuine, if modest, flow improvement without touching anything upstream of the cat: a straightforward bolt-on that doesn't need a remap or any other supporting mods to enjoy.
