Over time, constant thermal cycling, towing loads, and vibration induce micro-fractures along the factory welds and collector seams. Concurrently, the OEM ceramic washcoat suffers thermal sintering and oil-vapor contamination, depleting oxygen storage capacity and triggering persistent catalyst efficiency check engine lights while choking high-RPM exhaust expulsion.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from heavy-gauge stainless steel tubing, this direct-fit manifold converter pair resists thermal fatigue, oxidation, and road salt corrosion. High-efficiency ceramic monolith substrates maximize catalytic surface area to ensure rapid light-off and complete emissions conversion without generating restrictive exhaust backpressure. Precision laser-cut flanges prevent thermal warping, while factory-located O2 sensor bungs allow seamless plug-and-play installation utilizing the included gaskets and hardware.\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;\"\u003e2003-2009 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;\"\u003e1GR-FE (4.0L V6) \/ N210\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;\"\u003e245 hp \/ 282 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\u003e2003 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2005 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2008 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2009 Toyota 4Runner 4.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-mileage utility, this replacement assembly maintains the backpressure parameters necessary to safeguard low-end torque delivery during steep trail climbs and heavy trailer towing without recurring emissions faults.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489478152440,"sku":"DS-E3IZ1QKT0","price":156.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-4runner-2003-2009-4-0l-1.jpg?v=1789163282","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-toyota-4runner-2003-2009-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
