It replaces the exhaust from the rear axle back, the shortest section Milltek offers on this platform, swapping the factory tail section for wider-bore pipework and a silencer tuned for a sportier note. Everything ahead of the rear axle, including the mid-pipe, stays standard. It's offered in 5 tailpipe finishes, so you can pick the setup that suits how the car's used.\u003c\/p\u003e\n\u003cp\u003eIt's the option for a subtle, tail-end-only change in sound and look, rather than the fuller transformation of a cat-back or front-pipe-back system.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e Axle Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter:\u003c\/strong\u003e 80mm (3.15\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC Approved:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRace System:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Time:\u003c\/strong\u003e approx. 1.5 to 2 hours (Milltek figure)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMade from T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration\u003c\/li\u003e\n\u003cli\u003eMandrel-bent pipework keeps a constant diameter through every bend for unrestricted flow\u003c\/li\u003e\n\u003cli\u003e80mm (3.15\") pipework\u003c\/li\u003e\n\u003cli\u003eReplaces the rear section only; everything ahead of the rear axle stays standard\u003c\/li\u003e\n\u003cli\u003eChoice of 5 tailpipe finishes: GT-100 Brushed Titanium, GT-100 Burnt Titanium, JET-100 Carbon Fibre, GT-100 Cerakote Black, GT-100 Polished\u003c\/li\u003e\n\u003cli\u003eDesigned, developed and manufactured in the UK by Milltek Sport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 5 Series M5 \u0026amp; M5 Competition 4.4l Twin Turbo F90 (Non OPF\/GPF Cars) (2018-2020)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series M5 \u0026amp; M5 Competition 4.4l Twin Turbo F90 (North American\/ROW Cars) (2019 onwards)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series M5 \u0026amp; M5 Competition 4.4l Twin Turbo F90 (OPF\/GPF Equipped Cars) (2020-2021)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series M5 \u0026amp; M5 Competition 4.4l Twin Turbo F90 LCI (OPF\/GPF Equipped Cars) (2021 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the BMW 5 Series M5 4.4l Twin Turbo Hybrid G90 \u0026amp; G99 (NAS\/ROW Spec Vehicles), which needs the \u003ca href=\"\/products\/milltek-axle-back-exhaust-bmw-5-series-m5-4-4-twin-turbo-hybrid-g90-g99-nas-row-spec-25\"\u003eMilltek Axle Back Exhaust BMW 5 Series M5 4.4l Twin Turbo Hybrid G90 \u0026amp; G99 NAS \u0026amp; ROW Spec Vehicles 25+\u003c\/a\u003e; the BMW 5 Series M5 4.4l Twin Turbo Hybrid G90 \u0026amp; G99 (UK\/European Spec Vehicles), which needs the \u003ca href=\"\/products\/milltek-axle-back-exhaust-bmw-5-series-m5-4-4-twin-turbo-hybrid-g90-g99-uk-eu-spec-25\"\u003eMilltek Axle Back Exhaust BMW 5 Series M5 4.4l Twin Turbo Hybrid G90 \u0026amp; G99 UK \u0026amp; European Spec Vehicles 25+\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 1.5 to 2 hours.
