It replaces everything from the factory catalytic converter rearward with wider-bore pipework, a re-profiled mid-pipe and silencers tuned specifically for this platform, cutting back pressure and sharpening the exhaust note. The factory catalytic converter stays in place, so the car's emissions hardware is left as 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 aimed at owners who want a noticeably different sound and a genuine, if modest, flow improvement without touching anything upstream of the cat: a straightforward bolt-on that doesn't need a remap or any other supporting mods to enjoy.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e Cat-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 Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Time:\u003c\/strong\u003e approx. 2 to 3 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 standard exhaust from the catalytic converter back, so the factory cat is retained\u003c\/li\u003e\n\u003cli\u003eChoice of 5 tailpipe finishes: GT-115 Burnt Titanium, GT-115 Cerakote Black, GT-115 Polished, GT-115 Titanium, JET-115 Carbon Fibre\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 X3 X3M\/X3M Comp (G01) 3.0 (ROW \u0026amp; North American S58 Engine - LCI only) (2022 and Later) (2022 onwards)\u003c\/li\u003e\n\u003cli\u003eBMW X4 X4M\/X4M Comp (G02) 3.0 (ROW \u0026amp; North American S58 Engine - LCI only) (2022 and Later) (2022 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the BMW X3 X3M\/X3M Comp (G01) 3.0 (with OPF\/GPF S58 Engine - LCI only), which needs the \u003ca href=\"\/products\/milltek-downpipe-back-exhaust-bmw-x3-x3m-comp-g01-3-0-with-opf-gpf-s58-lci-22\"\u003eMilltek Downpipe-back Exhaust BMW X3 X3M \u0026amp; X3M Comp G01 3.0 (with OPF\/GPF S58 Engine - LCI only) 22+\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 2 to 3 hours.
