Unlock a richer soundtrack and a sharper rear end look for your BMW 3 Series F30 320i with the Milltek SSXBM1072 system. This UK-built stainless steel setup delivers a assertive non-resonated tone, a premium twin outlet conversion and beautiful mirror-finish GT90 tailpipes. Perfect for drivers who want a deeper, sportier sound and a clean dual-exit appearance that suits the F30 saloon. Part number: SSXBM1072.

Crafted in Britain from aircraft grade T304 stainless steel, this free-flowing system uses constant-radius bends and enlarged pipework for excellent gas velocity and long-term corrosion resistance. The non-res layout provides a louder, more engaging note while careful development helps keep unwanted cabin boom in check. The twin exit layout gives that sought-after M340i style rear end. Please note: the dual outlet design requires the M340i rear valance for correct fit and finish.
