The OEM units feature rough internal casting walls, abrupt angle transitions, and pinched runners that create localized backpressure zones. Subject to severe thermal cycling during towing or sustained hill climbs, these heavy cast units commonly suffer from warped mating surfaces, exhaust stud shear, and micro-cracking around the internal collector transitions, choking the natural scavenging efficiency of the \u003cstrong\u003e3UR-FE\u003c\/strong\u003e V8.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from mandrel-bent 16-gauge (1.5mm) 304 stainless steel, these tubular shorty headers provide smooth, unrestricted flow dynamics through dedicated 1-5\/8 in. (42mm) primaries merging into a 2-1\/2 in. (64mm) collector. Each head flange is precision laser-cut to 3\/8 in. (9.5mm) thickness and hydraulically flattened to maintain a reliable, leak-free seal across all exhaust ports. Complete TIG-welded construction eliminates structural weak points, providing high fatigue strength and corrosion resistance against severe heat soak without requiring custom exhaust modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Shorty exhaust headers (driver and passenger side)\u003c\/li\u003e\n  \u003cli\u003e2 Header-to-cylinder-head gaskets\u003c\/li\u003e\n  \u003cli\u003e2 Collector (outlet) gaskets\u003c\/li\u003e\n  \u003cli\u003eSecondary air port gaskets\u003c\/li\u003e\n  \u003cli\u003eMounting bolts and hardware set\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2008-2014 Toyota Sequoia\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\u003e3UR-FE\u003c\/strong\u003e \/ \u003cstrong\u003eXK60\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;\"\u003e381 hp \/ 401 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;\"\u003e\u003cstrong\u003eFE655410-32\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008-2014 Toyota Sequoia Base 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2008-2014 Toyota Sequoia SR5 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2008-2014 Toyota Sequoia Limited 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the XK60 Sequoia?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2014 Toyota Sequoia equipped with the 5.7L \u003cstrong\u003e3UR-FE\u003c\/strong\u003e engine; it does not fit models equipped with the 4.6L or 4.7L V8 engines.\u003c\/p\u003e\n\n\u003ch4\u003eAre modifications required for the secondary air injection system?\u003c\/h4\u003e\n\u003cp\u003eNo, these headers feature integrated secondary air injection ports and include dedicated port gaskets to retain full compatibility with the factory emissions configuration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Towing Caliber\u003c\/h3\u003e\n\u003cp\u003eHeavy-duty hauling and sustained highway grade climbing demand consistent thermal dissipation and uncompromised structural integrity.
