Over time, the stock ceramic brick suffers washcoat erosion, catalyst poisoning, and structural sintering. This breakdown leads to core meltdown or severe exhaust backpressure, robbing exhaust velocity from the \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e V8, reducing manifold scavenging, and tripping persistent downstream oxygen sensor check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit left and right catalytic converter assembly is engineered with a heavy-duty stainless steel outer shell designed to withstand rigorous off-road vibration and high exhaust gas temperatures (EGT). Inside, an optimized ceramic honeycomb substrate is coated with an advanced precious metal washcoat to maximize catalytic conversion efficiency without restricting flow. Precision-machined, thick OE-style flanges ensure leak-free mating with existing exhaust manifolds and mid-pipes. The direct replacement package includes required installation hardware and high-temp composite gaskets, retaining factory O2 sensor bungs for true plug-and-play installation without cutting or custom fabrication.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2011-2018 RAM 1500\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e5.7L HEMI V8 \/ DS Platform\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e395 hp \/ 410 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2018 RAM 1500 (5.7L V8 Gas, Left \u0026amp; Right Placement)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the DS 1500?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2018 RAM 1500 equipped with the \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this catalytic converter legal for road use in California?\u003c\/strong\u003e\u003cbr\u003e No, this unit is an EPA-compliant federal catalytic converter and cannot be legally sold or installed on vehicles registered in CARB-restricted states.\u003c\/p\u003e\n\n\u003ch3\u003eThe RAM Towing Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty cycles, heavy payload hauling, and intense grade towing, this emissions assembly restores low-end torque and high-temperature integrity to keep your truck running reliably under load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501730304248,"sku":"DS-E564RRSSV","price":321.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ram-1500-2011-2018-5-7l-left-right-1.jpg?v=1789331480","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-ram-1500-2011-2018-5-7l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
