Stainless Steel Exhaust Header Manifold for Chevy S10 & GMC Sonoma 4.3L V6 (4WD)

Eliminate cracks and restore performance. The factory cast iron manifolds on the 4.3L V6 are notorious for cracking, leaking, and restricting flow. Upgrade your 1996-2001 Chevy S10/Blazer or GMC Sonoma/Jimmy to our High-Performance T-304 Stainless Steel Header Manifold. Engineered for 4WD models with Air Injection, this 2-piece kit is the durable, high-flow solution your truck needs.

Why Upgrade to T-304 Stainless Steel?

Stock manifolds degrade over time due to heat cycles and rust. Our headers are manufactured from CNC machined T-304 stainless steel, offering superior resistance to corrosion and thermal stress.

  • Enhanced Durability: Computerized TIG welded flanges provide exceptional strength, ensuring a leak-free seal that outlasts OEM cast iron parts.
  • Optimized Flow: The 3-to-1 piping design reduces back pressure compared to stock, allowing your 4.3L Vortec engine to breathe better for improved throttle response.
  • Direct Fit Replacement: Designed with pre-welded hangers and OEM-spec geometry for a straightforward bolt-on installation—no cutting or heavy modification required.
  • OEM Quality: Produced by OEM-approved manufacturers using materials that meet or exceed original equipment standards.
