Each header is American-made from stainless steel and includes 3 inch slip-fit collectors paired with high-flow catalytic converters, so the system stays emissions-compliant while flowing better than stock. The catted lead pipes connect directly to your factory exhaust or a Stainless Works catback for a clean, complete installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1-7\/8 inch CNC mandrel-bent primary tubes for improved exhaust flow over factory manifolds\u003c\/li\u003e\n\u003cli\u003e3 inch slip-fit collectors for a secure, leak-resistant connection to the lead pipes\u003c\/li\u003e\n\u003cli\u003eIntegrated high-flow catalytic converters keep the system emissions-compliant while maximizing flow\u003c\/li\u003e\n\u003cli\u003eAmerican-made stainless steel construction resists corrosion and holds up to sustained exhaust heat\u003c\/li\u003e\n\u003cli\u003eLead pipes connect to factory exhaust or a Stainless Works catback system without additional fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\u003cth\u003eVehicle Application\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e2011-2026 Dodge Durango, 5.7L V8\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eStainless Works\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Tube Diameter\u003c\/td\u003e\n\u003ctd\u003e1-7\/8 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCollector Diameter\u003c\/td\u003e\n\u003ctd\u003e3 inch, slip-fit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalytic Converter\u003c\/td\u003e\n\u003ctd\u003eHigh-flow, integrated in lead pipes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Manufacture\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLong tube headers with 1-7\/8in primaries (2)\u003c\/li\u003e\n\u003cli\u003eHigh-flow catted lead pipes (2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout Stainless Works\u003c\/h4\u003e\n\u003cp\u003eStainless Works designs and manufactures American-made stainless steel exhaust systems and headers for street and performance applications, engineering each header and exhaust component specifically for the vehicle platform it fits.\u003c\/p\u003e\n\u003ch4\u003eRelated Parts\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/blackopsautoworks.com\/products\/stainless-works-2011-2025-durango-5-7l-catback-legend-black-tip\"\u003eStainless Works 2011-2025 Durango 5.7L Catback Legend Black Tip\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/blackopsautoworks.com\/products\/stainless-works-11-20-dodge-durango-5-7l-3in-redline-catback-w-4in-black-tips\"\u003eStainless Works 11-20 Dodge Durango 5.7L 3in Redline Catback\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFAQ\u003c\/h4\u003e\n\u003cstrong\u003eDo these headers require any cutting or modification to install?\u003c\/strong\u003e\n\u003cp\u003eNo. These headers are designed as a direct bolt-on replacement for the factory manifolds on the 2011-2026 Durango 5.7L, using the factory mounting points.\u003c\/p\u003e\n\u003cstrong\u003eWill these headers pass emissions inspection?\u003c\/strong\u003e\n\u003cp\u003eThe lead pipes include high-flow catalytic converters, so the system remains catted and is designed to be more emissions-friendly than a catless header setup.
