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 2 tailpipe finishes and a choice of modification (Not Required, Required), 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. 3 to 3.5 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 2 tailpipe finishes: Cerakote Black Oval, Polished Oval\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\u003eAudi RS6 C8 4.0 V8 bi-turbo in Performance Edition (Non OPF\/GPF Models - USA\/ROW Models) (2020 onwards)\u003c\/li\u003e\n\u003cli\u003eAudi RS6 C8 4.0 V8 bi-turbo in Performance Edition (OPF\/GPF Models) (2019 onwards)\u003c\/li\u003e\n\u003cli\u003eAudi RS7 C8 4.0 V8 bi-turbo (Non OPF\/GPF US\/ROW Models) (2019 onwards)\u003c\/li\u003e\n\u003cli\u003eAudi RS7 C8 4.0 V8 bi-turbo (OPF\/GPF Models) (2019 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Audi RS6 C8 4.0 V8 bi-turbo (Non OPF\/GPF Models- USA\/ROW) - Signature Series Titanium, which needs the \u003ca href=\"\/products\/milltek-filter-back-exhaust-audi-rs6-c8-4-0-v8-bi-turbo-opf-gpf-signature-series-titanium-19\"\u003eMilltek Filter-back Exhaust Audi RS6 C8 4.0 V8 bi-turbo OPF\/GPF - Signature Series Titanium 19+\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 3 to 3.5 hours.
