Milltek Sport Cat-Back Exhaust with OPF/GPF Bypass & Burnt Blue Titanium GT-100 Tips for BMW M5 F90 & M5 Competition 4.4 Twin-Turbo (2020+) - Stage 2 ECU Required - Track/Off-Road Use Only

Milltek Sport performance rear system with OPF GPF bypass and Burnt Blue Titanium GT-100 tailpipes for BMW F90 M5 and M5 Competition 2020 onwards

Give your S63-powered F90 the soundtrack it deserves. This UK-built Milltek Sport rear section replaces the factory back-half on OPF GPF cars and includes particulate filter bypass pipes plus striking GT-100 Burnt Blue Titanium quad outlets. Designed for vehicles running Stage 2 software, it unleashes a fuller, sharper V8 tone and improves flow to complement higher boost and tuning.

Why this upgrade stands out

• OPF GPF bypass sections included for maximum flow and sound on filter-equipped models
• GT-100 Burnt Blue Titanium quad tailpipes deliver an authentic motorsport finish and presence
• Crafted in the UK from T304 stainless steel for durability and corrosion resistance
• Constant-radius bends and enlarged tubing for smooth gas velocity and responsive feel
• Developed specifically for the F90 platform to deliver an engaging tone without harsh cabin boom
• Perfect partner for Stage 2 calibration and higher-output S63TU builds

What you can expect

Deeper, crisper, more characterful acoustics from idle to redline. More presence outside, refined inside. Robust UK manufacturing with premium materials that look as good as they perform. On our own cars and customer installs, feedback has been consistently positive regarding sound quality, finish and driveability.

Construction and finish

Milltek Sport uses high grade T304 stainless throughout the silencers and pipework, with precision mandrel bends to maintain consistent diameter through every sweep. The signature GT100 burnt blue titanium tips complete the rear with an eye-catching, heat-treated look that suits the F90’s wide stance.
