Milltek Performance Filter-Back Race System with Polished GT90 Tailpipes for BMW M3 F80 and M3 Competition Saloon 2019 to 2020 OPF GPF models - Part No. SSXBM1117

Unlock the true voice of the S55 with Milltek’s race-level filter-back system, finished with mirror-polished 90 mm GT tailpipe finishers. Designed for late BMW M3 F80 saloon models equipped with OPF and GPF hardware, this Milltek setup (part number SSXBM1117) delivers a fierce, motorsport-inspired soundtrack and sharper response while retaining the factory particulate filters.

Crafted in Britain from premium T304 grade non-magnetic stainless steel, the system uses precision mandrel-bent tubing for smooth, uninterrupted gas flow. The freer-flowing layout helps the turbocharged six breathe more easily, improving throttle pick-up and adding serious road presence. Milltek’s sound development minimises cabin boom for an addictive tone outside and comfortable refinement inside.

The GT90 polished outlets complete the rear with a clean, purposeful look that suits the F80’s aggressive styling. If you want a serious sound upgrade for your BMW M3 saloon without deleting the particulate filters, this is the high-quality, UK-built solution enthusiasts choose.
