Give your 428i the soundtrack and style it deserves. This UK-crafted Milltek system transforms your BMW F32 2.0 turbo with a richer, more purposeful tone and a premium black-tip finish, while keeping motorway manners calm and refined thanks to its silenced centre section. Built from genuine T304 stainless steel and engineered for smooth flow, it is a direct-fit upgrade that looks OEM-plus and sounds superb.

Why enthusiasts choose this Milltek upgrade

• Premium T304 stainless throughout for long-term corrosion resistance and lasting shine.
• Mandrel-bent pipework for uninterrupted gas flow and sharper throttle response.
• Silenced (resonated) layout for low drone at cruising speeds with a sporty growl under load.
• Factory-style twin exit with heat-resistant Cerakote black tailpipes for a stealth, factory-plus finish.
• Bolt-on, direct replacement using factory mounting points for a clean, hassle-free fit.

What it feels and sounds like on the road

We have installed this system for BMW 428i owners and the feedback has been consistently positive: deeper tone outside, refined inside, and a noticeable improvement in response from Milltek’s free-flowing design. The result is an everyday-friendly exhaust note with a sporty edge when you open it up — no harsh resonance, just quality sound.
