This B58 4.5-inch decat downpipe applies that principle to help limit heat transfer to surrounding components. Reducing radiant heat in the engine bay can also help limit intake-system heat soak and keep intake air temperatures lower.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHeat-shielded decat configuration.\u003c\/li\u003e\n\u003cli\u003eHand-crafted and TIG-welded 4.5-inch 304-grade stainless steel.\u003c\/li\u003e\n\u003cli\u003eCNC-machined 304-grade stainless-steel flange for a smooth transition.\u003c\/li\u003e\n\u003cli\u003eSmooth-radius bends designed to reduce turbulence.\u003c\/li\u003e\n\u003cli\u003eFits the stock cat-back and compatible aftermarket cat-back systems.\u003c\/li\u003e\n\u003cli\u003eFits right-hand-drive and left-hand-drive applications without modification.\u003c\/li\u003e\n\u003cli\u003eVRSF lifetime warranty for the race\/decat version.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUK Vehicle Fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW F20\/F21 M140i – B58 Gen-1 downpipe\/exhaust interface\u003c\/li\u003e\n\u003cli\u003eBMW F22\/F23 M240i – B58 Gen-1 downpipe\/exhaust interface\u003c\/li\u003e\n\u003cli\u003eBMW F30\/F31 340i – B58 Gen-1 downpipe\/exhaust interface\u003c\/li\u003e\n\u003cli\u003eBMW F32\/F33\/F36 440i – B58 Gen-1 downpipe\/exhaust interface\u003c\/li\u003e\n\u003cli\u003eBMW G30 540i – Gen-1 downpipe\/exhaust interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFitment check:\u003c\/strong\u003e Confirm the physical turbo-to-downpipe and downpipe-to-exhaust connections before ordering; model year alone is not sufficient.\u003c\/p\u003e","brand":"VRSF","offers":[{"title":"Default Title","offer_id":58560471728502,"sku":"10582018","price":480.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/1085\/2726\/files\/123.jpg?v=1787937630","url":"https:\/\/slnperformance.co.uk\/products\/vrsf-b58-4-5-decat-downpipe-with-heat-shield-bmw-m140i-m240i-340i-440i-540i","provider":"SLN Performance LTD","version":"1.0","type":"link"}
