The BD Diesel exhaust manifold kit steps in with a serious upgrade that is built to handle higher temperatures and long-term stress without giving in. With castings that are 65% thicker than stock, these manifolds are designed to resist cracking and warping, even when the engine is working hard during towing or heavy hauling. Additionally, the improved internal design increases exhaust flow by 5%, helping your turbo spool more efficiently and keeping performance consistent. The driver side manifold also eliminates the restriction found in early model years, which makes a noticeable difference when you are asking more from your truck. What's more, the high temperature coating adds another layer of protection against corrosion, so these manifolds stay reliable in all kinds of environments. This is the kind of upgrade that gives you confidence every time you put your foot down.\u003c\/p\u003e\n\u003ch4\u003eEngineered Flow And Strength For Long Lasting Performance Gains\u003c\/h4\u003e\n\u003cp\u003eThis manifold kit is built with high-silicon ductile iron, a material chosen for its ability to handle repeated heat cycles without losing structural integrity. The thicker wall design not only improves durability but also stabilizes exhaust temperatures, which can help protect surrounding components over time. Furthermore, the 5% increase in exhaust flow allows gases to move more efficiently toward the turbocharger, supporting better response and overall engine efficiency. The inclusion of a predrilled pyrometer port on the driver side makes it easy to monitor exhaust gas temperatures, which is especially useful for tuned or work-focused trucks. Installation is straightforward thanks to the complete kit design, which includes all necessary gaskets and fasteners for a true drop-in replacement. Designed specifically for 2001-2016 6.6L Duramax applications, this kit replaces the factory manifolds without modification. Backed by a 36 month or 75,000 mile warranty, it is a well-rounded solution for anyone looking to improve both reliability and performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNot legal for sale in California\u003c\/li\u003e\n\u003cli\u003eFits 2001-2016 6.6L Duramax engines\u003c\/li\u003e\n\u003cli\u003eReplaces both driver and passenger manifolds\u003c\/li\u003e\n\u003cli\u003eAddresses factory driver side restriction\u003c\/li\u003e\n\u003cli\u003eEstimated install time around 5 hours\u003c\/li\u003e\n\u003cli\u003eIncludes all required installation hardware\u003c\/li\u003e\n\u003cli\u003eEPA compliant for federal use\u003c\/li\u003e\n\u003cli\u003eBacked by 36 month warranty\u003c\/li\u003e\n\u003cli\u003e75,000 mile warranty coverage limit\u003c\/li\u003e\n\u003cli\u003eIdeal for towing and performance applications\u003c\/li\u003e\n\u003cli\u003eDirect replacement with no major modifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"file:\/\/\/C:\/Users\/edgar.ramirez\/Downloads\/(I-00103)%201041460%20Duramax%20Manifold.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"BD Diesel","offers":[{"title":"Default Title","offer_id":53990902530332,"sku":"BDD1041459","price":535.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/exhaust-manifold-kit-chevrolet-silverado-gmc-sierra-2500hd-and-3500hd-6-6l-duramax-2001-2016.webp?v=1773957270","url":"https:\/\/www.alligatorperformance.com\/products\/bd-diesel-1041459-exhaust-manifold-kit-2001-2016-gm-silverado-sierra-2500hd-3500hd-6-6l-duramax","provider":"Alligator Performance","version":"1.0","type":"link"}
