Milltek Sport FAP-back exhaust system for BMW X3 G01 X3M / X4 G02 X4M

Replacing the factory exhaust with a Milltek Sport FAP-back system brings back the character that the engine of your BMW X3 G01 X3M / X4 G02 X4M suppresses from the factory: a rounder tone at idle that opens up clearly through the rev range, with no gimmicks.

Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system remains mellow at steady cruising speed, ideal for daily driving.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. An equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

What owners mention most often in their feedback: fit quality and a deep tone that is present but never harsh. This is the signature of Milltek Sport, the British manufacturer specializing in stainless steel exhausts.
