The OEM cast-iron design features thick, uneven walls and sharp collector transitions that cause severe thermal shock over repeated heat cycles. Inevitably, hairline cracks develop along the runner junctions, introducing ambient oxygen into the exhaust stream. This false air skews upstream O2 sensor feedback, causes unmetered lean codes, drops low-end torque, and introduces audible exhaust ticks under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated from heavy-gauge \u003cstrong\u003eT304 stainless steel\u003c\/strong\u003e, this direct-fit header assembly eliminates brittle cast iron in favor of ductile, heat-resilient tubular runners. Mandrel-bent primary tubes maintain uniform cross-sectional area throughout each bend, reducing parasitic pumping losses and maximizing exhaust gas velocity. The precision TIG-welded collector optimizes pulse pairing from cylinder banks to enhance cylinder evacuation. Heavy-duty, laser-cut mounting flanges prevent thermal warping under demanding hauling duties, while pre-welded bungs maintain precise factory sensor orientation.\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;\"\u003e1995-2000 Toyota Tacoma\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\u003e5VZ-FE\u003c\/strong\u003e (3.4L V6) \/ \u003cstrong\u003eN140 \/ N150 \/ N160 \/ N170\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;\"\u003e190 hp \/ 220 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;\"\u003eSPT-EHD1220\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1995-2000 Toyota Tacoma Base 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e1995-2000 Toyota Tacoma DLX 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e1995-2000 Toyota Tacoma SR5 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e1998-2000 Toyota Tacoma PreRunner 3.4L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the N140 \/ N150 Tacoma?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1995-2000 Toyota Tacoma equipped with the \u003cstrong\u003e5VZ-FE\u003c\/strong\u003e 3.4L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to re-torque the hardware after installation?\u003c\/strong\u003e\u003cbr\u003e Yes, always re-torque the cylinder head flange fasteners after an initial 20-minute heat cycle to ensure the gasket maintains a permanent seal under thermal expansion.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained high exhaust gas temperatures during severe towing and rock crawling, this stainless manifold provides the heavy-duty structural integrity and corrosion resistance demanded by high-mileage first-generation Tacoma platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607326068984,"sku":"DS-EXXJWP8FY","price":322.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-toyota-tacoma-1995-2000-3-4l-1.jpg?v=1790091156","url":"https:\/\/performancechiptuning.com\/products\/exhaust-header-for-toyota-tacoma-1995-2000-3-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
