Unleash the full character of your new BMW F70 M135 xDrive with the Milltek Sport OPF/GPF-compatible exhaust system, available in both a road-legal OPF-back configuration and an optional cat-back upgrade featuring an OPF-delete midpipe. Designed specifically for the 2024+ F70 M135, this system enhances sound, performance, and aesthetics without compromising factory driveability or build quality. Crafted in the UK from high-grade T304L stainless steel, the system is mandrel-bent for optimal flow and durability. The OPF-back system offers a refined yet sporty tone while retaining the factory GPF/OPF, making it ideal for road use. For those seeking maximum sound and performance, the OPF-delete midpipe upgrade transforms the system into a full cat-back exhaust, delivering a more aggressive note and reduced backpressure—perfect for tuned or track-focused setups. To complete the package, Milltek offers a range of premium tailpipe options to suit your personal style, including Polished Chrome, Cerakote Black, Burnt Titanium, and Brushed Titanium finishes.
