Crafted entirely from lightweight titanium, this system is designed to enhance every aspect of the driving experience, from sound and performance to weight savings and aesthetics. More than just an exhaust, it's the finishing touch this genuinely underrated hot hatch deserves, how it should have come from the factory.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe Slip-On Line transforms the exhaust note entirely, delivering a smooth, refined tone at cruising speeds that opens up into a genuinely deeper, more purposeful growl under acceleration. Akrapovič's engineers retained the factory dual-mode, ECU-controlled valve from the original system, letting you switch seamlessly between a civilised, comfortable character for daily driving and a genuinely sportier, more aggressive note when you want it, all without any unwanted drone creeping in during either mode. Complex components, including the valve housings and collectors, are cast in Akrapovič's own in-house titanium foundry, a level of manufacturing precision that's difficult to replicate with off-the-shelf mandrel-bent pipework.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSpecifically engineered for OPF\/GPF-equipped models, this system is designed to work correctly alongside the factory particulate filter setup rather than requiring its removal, an important distinction from Akrapovič's non-OPF systems for other platforms, where fitment and emissions compliance can differ substantially. Titanium construction delivers a genuine weight saving over the factory steel exhaust, a real benefit for a rear-wheel-drive hot hatch where reducing mass toward the rear has a measurable effect on handling balance and agility. The system is finished with hand-crafted carbon-fibre tailpipes, included as standard.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eImportant installation note:\u003c\/strong\u003e fitting this system requires the stock exhaust to be cut, this is not a reversible bolt-on modification. Review Akrapovič's installation instructions carefully before starting, and if you're not confident doing this yourself, have it fitted by a workshop experienced with Akrapovič products.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eOptional upgrades available:\u003c\/strong\u003e Akrapovič also offers a matching Evolution Line Link Pipe Set (Stainless Steel) for this platform, which further deepens the exhaust note and adds additional weight savings when combined with this Slip-On Line, alongside an optional Sound Kit that lets you control the exhaust valves independently of the car's drive mode. Installing either of these optional upgrades will invalidate ECE type approval for the system as a whole.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose This Exhaust System\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eGenuine titanium construction throughout, delivering real weight savings over the factory steel exhaust\u003c\/li\u003e\n\u003cli\u003eSpecifically engineered for OPF\/GPF-equipped models, works correctly alongside the factory particulate filter\u003c\/li\u003e\n\u003cli\u003eRetains the factory dual-mode, ECU-controlled valve, refined at cruise, aggressive on demand\u003c\/li\u003e\n\u003cli\u003eIncludes hand-crafted carbon-fibre tailpipes as standard\u003c\/li\u003e\n\u003cli\u003eValve housings and collectors cast in Akrapovič's own in-house titanium foundry\u003c\/li\u003e\n\u003cli\u003eCompatible with the optional Evolution Link Pipe Set and Sound Kit for further customisation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eBMW M140i (F20), OPF\/GPF\u003c\/li\u003e\n\u003cli\u003eBMW M140i (F21), OPF\/GPF\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eInstallation note:\u003c\/strong\u003e the stock exhaust system must be cut to install this Slip-On system, this is a permanent modification.\u003c\/p\u003e","brand":"Akrapovič","offers":[{"title":"Default Title","offer_id":54548618182989,"sku":"S-BM\/T\/5H","price":3408.33,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Akrapovic_BMW_M140i_F20_F21_OPF_GPF_Slip-On_Line_Titanium_Exhaust_System.webp?v=1787219137","url":"https:\/\/i6tuning.com\/products\/akrapovic-bmw-m140i-f20-f21-opf-gpf-slip-on-line-titanium-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
