If you own an S10, you know the sound: that rhythmic ticking on cold starts from a cracked cast iron manifold. It's not just annoying; it's a sign that your factory exhaust system is robbing you of power and efficiency.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eStainless Steel Exhaust Header Manifold for Chevrolet S10 (4.3L Vortec 4WD)\u003c\/h2\u003e\n\u003cp\u003eThe factory exhaust manifolds on the 1996-2001 S10 are heavy cast iron logs designed for cheap manufacturing, not performance. Over time, the extreme heat cycles cause the iron to become brittle and crack, or warp at the flanges, leading to inevitable exhaust leaks. On the 4WD chassis, where airflow is limited by the cramped engine bay, this heat retention also cooks your starter and spark plug wires. This T-304 stainless steel header kit is the mechanical cure for these chronic issues.\u003c\/p\u003e\n\u003cp\u003eEngineered specifically for the \u003cstrong\u003e4WD T-Series chassis\u003c\/strong\u003e, these headers are bent to navigate the tight clearances around the front differential and steering shaft—an area where generic headers often fail to fit. The 3-to-1 design replaces the turbulent stock log with smooth, mandrel-bent primary tubes that merge into a 2-inch collector. This scavenging effect pulls exhaust gases out of the cylinder head more efficiently, unlocking the low-end torque the L35 Vortec is capable of producing.\u003c\/p\u003e\n\u003cp\u003eMost importantly, this specific kit preserves your emissions compliance. It features the correct ports for the \u003cstrong\u003eAir Injection (A.I.R.) system\u003c\/strong\u003e, allowing you to bolt everything up without deleting emissions equipment or triggering a Check Engine Light. With CNC-machined flanges and computerized TIG welds, you get a flat sealing surface that prevents gasket blowout, ensuring that once you bolt these on, they stay sealed.\u003c\/p\u003e\n\u003ch2\u003eWhy You Need This Upgrade\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetains Factory Emissions:\u003c\/strong\u003e Includes specific provisions for the Air Injection Reaction (A.I.R.) system to keep the ECU happy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminates Manifold Cracking:\u003c\/strong\u003e T-304 stainless steel withstands thermal expansion far better than stock cast iron.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Optimization:\u003c\/strong\u003e 1.5\" primaries merging into a 2.0\" collector improve exhaust velocity for better throttle response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4WD Specific Geometry:\u003c\/strong\u003e Designed to clear the front driveshaft and suspension components unique to the 4-wheel-drive S10.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeak-Free Sealing:\u003c\/strong\u003e Thick, CNC-machined flanges provide a level surface to prevent the dreaded exhaust tick.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable style=\"border-collapse: collapse; border: 1px solid #e0e0e0; margin-bottom: 20px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003e1996-2001 Chevrolet S10 (4WD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eEngine Code\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003e4.3L V6 OHV (L35 Vortec)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eProfessional Recommended (Tight Space)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eT-304 Stainless Steel \/ CNC Flanges\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003ePiping Specs\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eInlet: 1.5\" \/ Outlet: 2.0\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe S10 engine bay is notorious for being tight, especially on 4WD models.
