Milltek OPF/GPF-Back Performance Exhaust with Burnt Blue Titanium GT-100 Tips for BMW 5 Series M5 & M5 Competition F90 4.4 Twin Turbo (2020+)

Transform your F90 with a UK-crafted OPF-GPF rear section that unleashes V8 character and elevates the rear styling with striking Burnt Blue Titanium GT-100 tailpipe finishers. Purpose-built for the 2020+ BMW M5 and M5 Competition, this premium rear exhaust section delivers serious presence without tampering with the particulate filters or catalysts.

What makes this rear system a must-have

• UK engineered and hand-finished in high grade T304 stainless steel for long-term durability
• Mandrel-bent pipework and carefully chosen diameter to free up flow while preserving mid-range punch
• Refined acoustic tuning for a deeper, sportier V8 tone without intrusive cabin drone
• 100 mm GT-100 Burnt Blue Titanium tailpipes - a bold, motorsport-inspired look with an OEM-plus fit
• Designed for OPF-GPF equipped cars - performance sound upgrade with emissions hardware retained

Sound and driveability perfected

This OPF-GPF back rear section enhances the natural soundtrack of the 4.4 biturbo V8, adding a richer note and more presence under throttle while remaining civilised on the motorway. It is ideal if you want a meaningful uplift in sound and style without unwanted resonance.

Built to perform and last

Constructed from non-magnetic T304 stainless throughout, with smooth-radius bends for consistent gas velocity. The result is a robust, corrosion-resistant system that looks as good as it sounds, with craftsmanship you can see in every weld and trim.

Burnt Blue Titanium GT-100 tips

The 100 mm GT-100 Titanium blue finishers completely refresh the rear of the F90, delivering a premium, aggressive appearance that pairs perfectly with the enhanced soundtrack.
