Prolonged thermal cycles and unburned hydrocarbons degrade the substrate, causing catalyst breakdown and chronic P0420\/P0430 DTCs. Simultaneously, factory Y-pipe merge junctions suffer from internal carbon buildup and thermal stress cracking along OEM seam welds, choking exhaust flow and sapping low-end torque on Chrysler \u003cstrong\u003ePowerTech\u003c\/strong\u003e powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on replacement, this unit features a robust 409 stainless steel outer casing mated to high-efficiency ceramic honeycomb monolith substrates washcoated with precious-metal catalyst loadings. Mandrel-bent Y-pipe runners optimize downstream velocity while reducing parasitic backpressure. Factory-located oxygen sensor bungs and heavy-duty, robotic TIG-welded flanges interface directly with OEM exhaust manifolds and intermediate pipes, eliminating the need for cutting or custom fabrication while withstanding the severe vibration of heavy hauling.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2006-2007 Dodge 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;\"\u003e3.7L V6 (\u003cstrong\u003eEKG\u003c\/strong\u003e) \/ 4.7L V8 (\u003cstrong\u003eEVA\u003c\/strong\u003e) \/ \u003cstrong\u003eDR\u003c\/strong\u003e\n\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;\"\u003e215-235 hp \/ 235-300 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;\"\u003e\n\u003cstrong\u003e55366588AD\u003c\/strong\u003e, \u003cstrong\u003e55366588AF\u003c\/strong\u003e, 50368, 20444\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2007 Dodge Ram 1500 3.7L V6 (PowerTech)\u003c\/li\u003e\n  \u003cli\u003e2006-2007 Dodge Ram 1500 4.7L V8 (PowerTech)\u003c\/li\u003e\n  \u003cli\u003eLeft and Right assembly; excludes 5.7L HEMI V8 models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the DR Ram 1500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2007 Dodge Ram 1500 equipped with the 3.7L V6 (\u003cstrong\u003eEKG\u003c\/strong\u003e) or 4.7L V8 (\u003cstrong\u003eEVA\u003c\/strong\u003e) engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs this unit legal for road use in California or CARB-compliant states?\u003c\/h4\u003e\n\u003cp\u003eNo, this assembly is EPA 46-state legal and cannot be sold, shipped, or installed on vehicles registered in California, Colorado, New York, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle continuous high-duty-cycle operating temperatures under heavy towing and payload stress, this converter assembly restores critical low-end scavenging and structural durability on your Ram truck.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537747149048,"sku":"DS-E9SN24A74","price":216.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-dodge-ram-1500-2006-2007-3-7l-4-7l-left-right-3.jpg?v=1790616785","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-dodge-ram-1500-2006-2007-3-7l-4-7l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
