Milltek SSXBM1128 OPF/GPF Delete & Decat Downpipes for BMW M3 F80 2019-2020 (Competition Saloon) - Turbo Outlet/Front Pipes, Catless S55 Exhaust Upgrade, OPF Bypass/GPF Removal, T304 Stainless

Milltek Sport OPF bypass front pipes and catalyst delete for BMW M3 F80 2019 to 2020 OPF cars – Part No. SSXBM1128

Give your F80-generation M3 the exhaust flow and soundtrack it should have left the factory with. Milltek’s high-flow turbo outlet pipes replace the restrictive particulate filters and factory cats on late EU6 models, transforming response and unlocking a harder-edged, motorsport tone. Built in the UK from premium T304 stainless steel, this SSXBM1128 assembly is engineered for enthusiasts who want maximum gas flow, durability and that unmistakable Milltek quality.

Key reasons to choose SSXBM1128

• High-flow turbo outlet pipes with particulate filter bypass and catalyst delete for maximum exhaust throughput.
• Made in the UK from aerospace-grade T304 stainless steel for strength, longevity and corrosion resistance.
• Mandrel-bent tubing maintains a consistent diameter for optimised gas velocity and reduced back pressure.
• Sharper, louder, more aggressive exhaust character that suits the S55 twin-turbo straight-six.
• Precision build quality that fits like OEM and stands up to track use.
