It replaces everything downstream of the factory diesel or petrol particulate filter with wider-bore pipework and re-tuned silencers, cutting back pressure and sharpening the exhaust note. The filter itself is left exactly where the manufacturer fitted it, so emissions equipment is unaffected. 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 right choice if you want a sportier sound and a genuine, if modest, flow improvement on a filter-equipped car, without going anywhere near the parts of the system that keep it emissions-compliant.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e Particulate Filter-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. 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\u003eFits behind the factory particulate filter, which stays in place\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 X3 X3M\/X3M Comp (G01) 3.0 (with OPF\/GPF S58 Engine - LCI only) (2022 onwards)\u003c\/li\u003e\n\u003cli\u003eBMW X3 X3M\/X3M Comp (G01) 3.0 (with OPF\/GPF S58 Engine - Pre LCI only) (2019-2021)\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\u003cli\u003eBMW X4 X4M\/X4M Comp (G02) 3.0 (with OPF\/GPF S58 Engine - LCI only) (2022 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e any model, engine or body style not listed above.
