Over time, extreme heat cycling causes the factory welded collector seams to develop micro-fractures, producing an audible cold-start exhaust tick. Simultaneously, high-mileage ceramic washcoats degrade and lose catalytic reduction efficiency, triggering persistent P0420\/P0430 trouble codes. Substrate sintering or internal crumbling further restricts exhaust gas flow, elevating cylinder head backpressure and dulling throttle response under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit front left assembly is manufactured from heavy-gauge stainless steel to resist rust, warping, and vibrational cracking across tough terrain. Internally, a dense ceramic honeycomb monolith wash-coated with targeted precious metals maximizes surface area contact, accelerating the conversion of hydrocarbons, carbon monoxide, and NOx into inert gases. Built with thick, precision-machined flanges and robotic TIG welds, it matches factory manifold drops to prevent exhaust leaks. The unit aligns with existing OEM downstream head-pipe routing and integrates factory-position O2 sensor bungs, eliminating the need for cutting, bending, or custom exhaust fabrication.\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;\"\u003e2005-2009 Toyota 4Runner\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;\"\u003e2UZ-FE 4.7L V8 \/ N210\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;\"\u003e270 hp \/ 330 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\u003e2005 Toyota 4Runner 4.7L V8 (Limited, SR5, Sport)\u003c\/li\u003e\n  \u003cli\u003e2006 Toyota 4Runner 4.7L V8 (Limited, SR5, Sport)\u003c\/li\u003e\n  \u003cli\u003e2007 Toyota 4Runner 4.7L V8 (Limited, SR5, Sport)\u003c\/li\u003e\n  \u003cli\u003e2008 Toyota 4Runner 4.7L V8 (Limited, SR5, Sport)\u003c\/li\u003e\n  \u003cli\u003e2009 Toyota 4Runner 4.7L V8 (Limited, SR5, Sport)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the N210 4Runner?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2009 Toyota 4Runner equipped with the 4.7L \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this clear a catalyst efficiency P0430 diagnostic trouble code?\u003c\/strong\u003e\u003cbr\u003e Yes, assuming functioning upstream\/downstream oxygen sensors, replacing a degraded Bank 2 converter with this federal-compliant assembly restores catalyst efficiency above the DTC threshold.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n\u003cp\u003eThe 4Runner platform is engineered for long-term utility, high payload ratings, and rugged off-road operation.
