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, 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 63.5mm (2.5\")\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\u003e63.5mm (2.5\") 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, GT-100 Burnt Titanium, GT-100 Cerakote Black, GT-100 Polished, GT-100 Titanium, JET-100 Carbon Fibre, Polished Oval\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\u003cli\u003eAudi S4 3.0 Turbo V6 B9 - Saloon\/Sedan \u0026amp; Avant (NON GPF ONLY - Sport Diff Models Only \u0026amp; Without Brace Bars) - Right Hand Drive Cars Only (2016 onwards)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Audi S4 3.0 Turbo V6 B9 - Saloon\/Sedan \u0026amp; Avant (NON GPF ONLY - Sport Diff Models Only \u0026amp; Without Brace Bars) - Left Hand Drive Cars Only, which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-audi-s4-3-0-turbo-v6-b9-saloon-avant-non-gpf-sport-diff-without-brace-bars-lhd-16\"\u003eMilltek Cat-back Exhaust Audi S4 3.0 Turbo V6 B9 - Saloon \u0026amp; Avant (NON GPF - Sport Diff \u0026amp; Without Brace Bars) - Left Hand Drive Cars 16+\u003c\/a\u003e; the Audi S4 3.0 Turbo V6 B9 - Saloon\/Sedan \u0026amp; Avant (NON GPF ONLY - Non Sport Diff Models) - Right Hand Drive Cars Only, which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-audi-s4-3-0-turbo-v6-b9-saloon-avant-non-gpf-non-sport-diff-rhd-16\"\u003eMilltek Cat-back Exhaust Audi S4 3.0 Turbo V6 B9 - Saloon \u0026amp; Avant (NON GPF - Non Sport Diff Models) - Right Hand Drive Cars 16+\u003c\/a\u003e; the Audi S4 3.0 Turbo V6 B9 - Saloon\/Sedan \u0026amp; Avant (NON GPF ONLY - Non Sport Diff Models) - Left Hand Drive Cars Only, which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-audi-s4-3-0-turbo-v6-b9-saloon-avant-non-gpf-non-sport-diff-lhd-16\"\u003eMilltek Cat-back Exhaust Audi S4 3.0 Turbo V6 B9 - Saloon \u0026amp; Avant (NON GPF - Non Sport Diff Models) - Left Hand Drive Cars 16+\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eWe recommend professional fitting on a ramp.
