When the \u003cstrong\u003e2ZR-FXE\u003c\/strong\u003e repeatedly switches between electric and combustion modes, unburnt fuel vapor and sudden exhaust quenching degrade the OEM ceramic monolith over time. This thermal shock leads to washcoat micro-fractures, catalyst passivation, reduced oxygen storage capacity, and restrictive flow bottlenecks that compromise combined powertrain efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured with a high-grade stainless steel shell and an advanced ceramic substrate washcoated with precious metal loadings, this unit restores OEM-level conversion rates without flow restriction. Automated robotic welds seal the collector and flange junctions against leaks, while mandrel-formed geometry preserves laminar flow dynamics. The direct-bolt assembly bolts directly up to existing hangers and manifold flanging, including replacement seals and hardware for a gas-tight seal that restores downstream O2 sensor readouts to factory spec.\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;\"\u003e2016-2019 Toyota Prius (1.8L L4)\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;\"\u003e\n\u003cstrong\u003e2ZR-FXE\u003c\/strong\u003e \/ \u003cstrong\u003eXW50\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;\"\u003e121 hp \/ 105 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\u003e2016-2019 Toyota Prius (Two, Three, Four, Touring) 1.8L Hybrid\u003c\/li\u003e\n  \u003cli\u003e2016-2019 Toyota Prius Two Eco 1.8L Hybrid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the XW50 Prius?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2016-2019 Toyota Prius equipped with the \u003cstrong\u003e2ZR-FXE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this direct-fit unit clear a recurring P0420 catalytic efficiency code?\u003c\/strong\u003e\u003cbr\u003e Yes, its premium active substrate restores the OEM oxygen storage capacity needed to clear downstream sensor fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to match strict JDM emissions calibration and thermal recovery demands, this unit ensures immediate closed-loop fuel trimming without check-engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501694259448,"sku":"DS-EY2S2V325","price":180.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-prius-2016-2019-1-8l-rear-left-right-1.jpg?v=1789329500","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-toyota-prius-2016-2019-1-8l-rear-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
