Carbon accumulation and melted internal matrices restrict exhaust gas velocity, drastically increasing cylinder backpressure. This bottleneck chokes mid-range torque, degrades fuel efficiency, and triggers recurrent P0420 diagnostic trouble codes due to insufficient oxygen storage capacity.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement unit features a high-density, uniform ceramic honeycomb substrate coated with precious metals to ensure efficient chemical conversion and lower emissions. The internal monolith is encapsulated in heavy-gauge stainless steel tubing that resists rust, road salt corrosion, and off-camber torsional stress. Robotically welded factory-matched flanges ensure an airtight seal against original downpipe mating surfaces without custom fabrication or pipe modification.\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;\"\u003e1996-2000 Toyota 4Runner\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;\"\u003e5VZ-FE \/ N180\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;\"\u003e183 hp \/ 217 lb-ft (Approx)\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;\"\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\u003e1996-2000 Toyota 4Runner Base 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Toyota 4Runner SR5 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Toyota 4Runner Limited 3.4L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Trail Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the harsh demands of trail crawling and heavy towing, this converter assembly restores critical low-end hauling torque and uninhibited exhaust evacuation across challenging terrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489478480120,"sku":"DS-ELU7Y3ARV","price":143.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-4runner-1996-2000-3-4l-1.jpg?v=1789163315","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-toyota-4runner-1996-2000-3-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
