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 resonated EC approved or non-resonated versions, 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\u003eTip Style:\u003c\/strong\u003e Twin 90mm GT90\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\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\u003eBMW 3 Series F30 328i M Sport Automatic (without Tow Bar, Non-xDrive \u0026amp; N20 Engine Only) (2012-2015)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the BMW 3 Series F30 320i M Sport Saloon (LCI models, Non-xDrive, Non-OPF \u0026amp; B48 Engine), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-bmw-3-series-f30-320i-m-sport-saloon-lci-non-xdrive-non-opf-b48-15-19\"\u003eMilltek Cat-back Exhaust BMW 3 Series F30 320i M Sport Saloon (LCI models, Non-xDrive, Non-OPF \u0026amp; B48 Engine) 15-19\u003c\/a\u003e; the BMW 3 Series F30 320i L M Sport Saloon (Long wheelbase) (LCI models, Non-xDrive, Non-OPF \u0026amp; B48 Engine), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-bmw-3-series-f30-320i-l-m-sport-saloon-lwb-lci-non-xdrive-non-opf-b48-15-19\"\u003eMilltek Cat-back Exhaust BMW 3 Series F30 320i L M Sport Saloon Long wheelbase (LCI models, Non-xDrive, Non-OPF \u0026amp; B48 Engine) 15-19\u003c\/a\u003e; the BMW 3 Series F80 M3, M3 Competition \u0026amp; M3 CS Saloon (OPF\/GPF Models Only), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-bmw-3-series-f80-m3-comp-cs-saloon-opf-gpf-19-20\"\u003eMilltek Cat-back Exhaust BMW 3 Series F80 M3, M3 Comp M3 CS Saloon OPF\/GPF 19-20\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eSome versions: Requires 335i rear valance.
