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 non-resonated or resonated EC approved versions and 7 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 76.2mm (3\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRace System:\u003c\/strong\u003e No\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\u003eReplaces the standard exhaust from the catalytic converter back, so the factory cat is retained\u003c\/li\u003e\n\u003cli\u003eChoice of 7 tailpipe finishes: Cerakote Black Oval, Polished Oval, GT-100 Burnt Titanium, JET-102 Carbon Fibre, GT-100 Cerakote Black, GT-100 Polished, GT-100 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\u003eAudi S3 2.0 TFSI quattro 3-Door 8V.2 (GPF Equipped Models Only) (2019-2020)\u003c\/li\u003e\n\u003cli\u003eAudi S3 2.0 TFSI quattro 3-Door 8V\/8V.2 (Non-GPF Equipped Models Only) (2013-2018)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNot every version fits every car in this list.
