The constant Atkinson-cycle start-stop duty cycle induces thermal shock that breaks down OEM ceramic substrates, generating restrictive backpressure spikes and persistent P0420 DTCs. Additionally, high OEM precious metal concentrations make factory units prime targets for theft, requiring a complete, bolt-in exhaust replacement.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit assembly is built with a heavy-gauge 409 stainless steel outer casing designed to resist corrosion and thermal warping under continuous thermal cycling. Internally, a high-efficiency ceramic honeycomb monolith features an optimized washcoat distribution that facilitates rapid catalyst light-off and stable NOx\/HC reduction without impeding exhaust velocity. Precision-machined flanges, pre-welded O2 sensor bungs, and included hardware allow a leak-free installation directly to stock hanger locations.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2009 Toyota Prius\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1NZ-FXE 1.5L \/ NHW20\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e76 hp \/ 82 lb-ft (Gas Engine)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eBER269295 \/ 1741021500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Toyota Prius Base 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n  \u003cli\u003e2005 Toyota Prius Base 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n  \u003cli\u003e2006 Toyota Prius Base 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n  \u003cli\u003e2007 Toyota Prius Base \/ Touring 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n  \u003cli\u003e2008 Toyota Prius Base \/ Touring 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n  \u003cli\u003e2009 Toyota Prius Base \/ Touring 1.5L L4 Electric\/Gas (1NZ-FXE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Efficiency Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to maintain proper exhaust scavenging and engine management closed-loop operation, this unit prevents CEL triggers while preserving hybrid fuel economy standards.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50484871463160,"sku":"DS-EEO43FSTG","price":159.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-prius-2004-2009-1-5l-1.jpg?v=1789107521","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-toyota-prius-2004-2009-1-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
