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 resonated EC approved or race non-resonated versions and 6 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\u003eRace System:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Time:\u003c\/strong\u003e approx. 1 to 1.5 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 6 tailpipe finishes: GT-115 Burnt Titanium, JET-115 Carbon Fibre, GT-115 Cerakote Black, GT-115 Polished, GT-115 Titanium, GT-115 Brushed Titanium\u003c\/li\u003e\n\u003cli\u003eEC approved versions available\u003c\/li\u003e\n\u003cli\u003eResonated (quieter) or non-resonated (louder) versions\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\u003eVolkswagen Golf Mk8 GTi (245ps Non-GPF\/North American Models Only) (2021-2024)\u003c\/li\u003e\n\u003cli\u003eVolkswagen Golf Mk8 GTi (245ps OPF\/GPF Equipped Models Only) (2020-2024)\u003c\/li\u003e\n\u003cli\u003eVolkswagen Golf Mk8 GTi Clubsport (300ps OPF\/GPF Equipped Models Only) (2021-2024)\u003c\/li\u003e\n\u003cli\u003eVolkswagen Golf Mk8.5 GTi (265ps OPF\/GPF Equipped Models Only) (2024 onwards)\u003c\/li\u003e\n\u003cli\u003eVolkswagen Golf Mk8.5 GTi Clubsport (300ps OPF\/GPF Equipped Models Only) (2024 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Volkswagen Golf Mk8 R 2.0 TSI 320PS (GPF Equipped Models Only), which needs the \u003ca href=\"\/products\/milltek-filter-back-exhaust-volkswagen-golf-mk8-r-2-0-tsi-gpf-21-24\"\u003eMilltek Filter-back Exhaust Volkswagen Golf Mk8 R 2.0 TSI GPF 21-24\u003c\/a\u003e; the Volkswagen Golf Mk8 GTi (Golf R Style Quad Outlet - 245ps OPF\/GPF Equipped Models Only), which needs the \u003ca href=\"\/products\/milltek-filter-back-exhaust-volkswagen-golf-mk8-gti-golf-r-style-quad-outlet-245ps-opf-gpf-20-24\"\u003eMilltek Filter-back Exhaust Volkswagen Golf Mk8 GTi (Golf R Style Quad Outlet - 245ps OPF\/GPF Equipped Only) 20-24\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 1 to 1.5 hours.
