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, non-resonated or resonated versions, 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 76.2mm (3\")\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\u003e76.2mm (3\") pipework\u003c\/li\u003e\n\u003cli\u003eFits behind the factory particulate filter, which stays in place\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\u003eAudi SQ7 4.0 V8 TT (Gasoline Non-OPF Equipped Vehicles Pre Facelift) (2021 onwards)\u003c\/li\u003e\n\u003cli\u003eAudi SQ7 4.0 V8 TT (Petrol OPF\/GPF Equipped Vehicles Pre Facelift) (2021-2024)\u003c\/li\u003e\n\u003cli\u003eAudi SQ8 4.0 V8 Bi-Turbo (Non OPF\/GPF Equipped Models Pre Facelift) (2020-2024)\u003c\/li\u003e\n\u003cli\u003eAudi SQ8 4.0 V8 Bi-Turbo (Petrol OPF\/GPF Equipped Models Pre Facelift) (2020-2024)\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.
