With a sleek brushed finish and TIG welded to perfection from 100% 304 grade stainless steel, we are certain that you will be delighted with the result. The manifolds are a strict upgrade from the OEM and are ideal as either a direct replacement, aftermarket upgrade or fitted in conjunction with one of our exhaust systems for 911 991.1 Turbo. The increased bore size translates to more free-flowing engine gases, leading to performance gains in terms of both HP and torque. Direct fit part for all  991 Turbo fitments, 2013-2019, including Turbo, Turbo S and Turbo Cabriolet models. Bolt on replacement with no cutting or welding required, however re-use of OEM factory gaskets is required. \u003c\/p\u003e\n\u003cp\u003eUnlike the 996 and 997 Turbo, the 991 headers are very restrictive and the clam shell design prohibits the turbos from spooling up quickly. These beautiful tubular stainless steel headers solve this problem through superior design and a sleek 3-1 collector.\u003c\/p\u003e\n\u003cp\u003ePrimary Diameter = Primary External Diameter 41mm \u003c\/p\u003e\n\u003cp\u003eCollectors Diameter = Collector External Diameter 44mm\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eBore Diameter-  44MM\u003cbr\u003eProduct Weight (boxed)- Box 1: 7KG\u003cbr\u003ePackage Dimensions- Box 1: 46x39x28 (CM)\u003cbr\u003eGaskets\/Fitting Kit- Not included\u003cbr\u003eVideo\/Sound Clip- Not yet sourced, we can offer a 30% refund on receipt\u003cbr\u003eInstallation instructions- Not included, we recommend professional installation\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eVideo below of a 991.1 with These manifolds and our Titanium exhaust installed\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"ratio ratio-16x9 mb-3 product-iframe\"\u003e\u003ciframe allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" data-src=\"https:\/\/www.youtube.com\/embed\/KbiHhVcNUao\" frameborder=\"0\" height=\"315\" loading=\"lazy\" title=\"YouTube video player\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Dragon","offers":[{"title":"Default Title","offer_id":51430164857098,"sku":"110017","price":599.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/8355\/8666\/files\/03c88dd89aef2a0543fe69cf16189550-fj.jpg?v=1751376034","url":"https:\/\/dragonexhausts.com\/products\/porsche-911-991-1-991-2-turbo-exhaust-manifolds-139","provider":"Dragon Exhausts ","version":"1.0","type":"link"}
