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 EC approved or resonated versions, 9 tailpipe finishes and valved or non-valved 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 70mm (2.76\")\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. 1 to 1.5 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\u003e70mm (2.76\") 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 9 tailpipe finishes: GT-100 Black, GT-100 Burnt Titanium, GT-100 Polished, GT-100 Titanium, GT-100 Cerakote Black, GT-90 Black, GT-90 Polished, GT-90 Titanium and more\u003c\/li\u003e\n\u003cli\u003eEC approved versions available\u003c\/li\u003e\n\u003cli\u003eValved versions available for switchable volume\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\u003eFord Mustang 5.0 V8 GT (Fastback) (2015-2018)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Ford Mustang 5.0 V8 GT (S650 Fastback), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-ford-mustang-5-0-v8-gt-s650-fastback-24\"\u003eMilltek Cat-back Exhaust Ford Mustang 5.0 V8 GT S650 Fastback 24+\u003c\/a\u003e; the Ford Mustang 5.0 V8 GT (Fastback - Facelift Model), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-ford-mustang-5-0-v8-gt-fastback-facelift-19\"\u003eMilltek Cat-back Exhaust Ford Mustang 5.0 V8 GT Fastback - Facelift Model 19+\u003c\/a\u003e; the Ford Mustang 5.0 V8 Dark Horse (S650 Fastback), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-ford-mustang-5-0-v8-dark-horse-s650-fastback-24\"\u003eMilltek Cat-back Exhaust Ford Mustang 5.0 V8 Dark Horse S650 Fastback 24+\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 1 to 1.5 hours.
