Milltek Cat-back Exhaust for Ford Bronco 6th Gen - 2.3l i4 & 2.7l V6 Ecoboost (4 Door Model Only) (2021 onwards) – Sharper Sound, Reduced Back Pressure

This is Milltek's cat-back system for the Ford Bronco 6th Gen - 2.3l i4 & 2.7l V6 Ecoboost (4 Door Model Only). 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 5 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.
