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 versions and 4 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 Primary 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 115mm GT115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC Approved:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRace System:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Time:\u003c\/strong\u003e approx. 0 to 1 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\u003eReplaces the standard exhaust from the catalytic converter back, so the factory cat is retained\u003c\/li\u003e\n\u003cli\u003eChoice of 4 tailpipe finishes: GT-115 Brushed Titanium, GT-115 Burnt Titanium, GT-115 Cerakote Black, GT-115 Polished\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\u003eToyota\/Lexus Corolla GR Corolla 1.6 Turbo (Manual Only) (2023 onwards)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Toyota\/Lexus GX GX550 3.4 Turbo V6, which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-toyota-lexus-gx-gx550-3-4-turbo-v6-24\"\u003eMilltek Cat-back Exhaust Toyota Lexus GX GX550 3.4 Turbo V6 24+\u003c\/a\u003e; the Toyota\/Lexus Land Cruiser 2.4L Turbo Hybrid (NAS Models), which needs the \u003ca href=\"\/products\/milltek-cat-back-exhaust-toyota-lexus-land-cruiser-2-4l-turbo-hybrid-nas-24\"\u003eMilltek Cat-back Exhaust Toyota Lexus Land Cruiser 2.4L Turbo Hybrid NAS 24+\u003c\/a\u003e; the Toyota\/Lexus Yaris Gen 1 - GR \u0026amp; GR Circuit Pack 1.6T (OPF\/GPF Models Only), which needs the \u003ca href=\"\/products\/milltek-toyota-yaris-gen-1-gr-circuit-pack-1-6t-opf-gpf-20-24\"\u003eMilltek Toyota \u0026amp; Lexus Yaris Gen 1 GR \u0026amp; GR Circuit Pack 1.6T OPF\/GPF Only 20-24\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eMilltek quotes a fitting time of approx. 0 to 1 hours.
