The factory catalytic converters on the \u003cstrong\u003e3.6L Pentastar\u003c\/strong\u003e engine frequently suffer from washcoat degradation, ceramic substrate fracturing, or carbon-fouled matrix channels. Once the OEM substrate breaks down, exhaust backpressure spikes—restricting engine breathing, driving up cylinder head temperatures, and triggering persistent P0420 and P0430 diagnostic trouble codes that lock the ECU into fuel-trim compensation maps.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement bank-to-bank catalytic converter assembly delivers an exact bolt-on solution engineered to stock exhaust geometry. Encased in heavy-gauge 409 stainless steel to withstand road debris and corrosive road salts, the unit houses a high-flow, heat-resistant ceramic honeycomb substrate coated with precious catalytic metals (Pt, Pd, Rh). Precision-machined, thick-gauge mounting flanges and pre-positioned factory-spec oxygen sensor bungs eliminate the need for custom cutting or welding. High-integrity welded seams ensure zero exhaust gas leaks, while included hardware and crush seals guarantee a gas-tight seal under heavy payload torque loads.\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;\"\u003e2014-2021 RAM ProMaster\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;\"\u003e3.6L Pentastar V6 (ERB) \/ VF Chassis\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;\"\u003e280 hp \/ 260 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\u003e2014-2021 RAM ProMaster 1500 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2021 RAM ProMaster 2500 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2021 RAM ProMaster 3500 3.6L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the VF ProMaster?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2014-2021 RAM ProMaster equipped with the \u003cstrong\u003e3.6L Pentastar\u003c\/strong\u003e engine on the \u003cstrong\u003eVF\u003c\/strong\u003e chassis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this assembly resolve active P0420 and P0430 DTC codes?\u003c\/strong\u003e\u003cbr\u003e Yes, assuming no upstream air-fuel ratio or ignition misfires exist, the high-efficiency catalytic core restores standard emissions conversion rates and clears efficiency codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe RAM Heavy-Duty Commercial Benchmark\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe fleet service and maximum payload demands, this emissions system eliminates power-robbing backpressure to keep commercial vans moving safely and efficiently under heavy payloads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501727518968,"sku":"DS-EBE25H9ZG","price":298.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ram-promaster-2014-2021-3-6l-left-right-1.jpg?v=1789331285","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-ram-promaster-2014-2021-3-6l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
