Long Tube Headers vs. Manifold: Why Headers Are the Best Upgrade for Your 351M/400M V8

The key difference between long tube headers and manifolds lies in both material and performance. Headers, made from lightweight, high-quality steel, are designed to optimize exhaust flow. Unlike thick iron manifolds, long tube headers feature longer, individual tubes for each cylinder, which helps eliminate back pressure. This results in increased horsepower and improved engine efficiency.

Upgrading to Flashark Long Tube Headers will enhance your Ford Bronco or F-Series truck’s engine performance and exhaust sound. Designed for 351M/400M V8 engines, these headers are engineered for maximum power with an easy, direct bolt-on installation—no modifications needed, whether you're on daily drives or off-road adventures.

Why Choose Our Natural Stainless Steel Long Tube Headers Over Black-Coated Alternatives?

While some competitors offer black-coated headers for a "stealth" look, our untreated stainless steel 351M/400M headers provide superior durability and long-term performance without compromises.

• No Peeling or Fading – Black coatings often chip, flake, or discolor under extreme heat, leaving a patchy, worn appearance. Our bare stainless steel maintains its integrity for years, resisting corrosion and wear.
  
• Better Heat Dissipation – Coatings can trap heat, reducing efficiency. Unpainted stainless steel allows optimal thermal transfer, helping your engine run cooler.
  
• Zero Maintenance – Unlike coated headers that require touch-ups, our stainless steel finish stays clean with minimal care—no worries about scratched paint or rust spots.
  
• Proven Material Quality – High-grade 304 stainless steel naturally resists oxidation, so it won’t degrade like cheap painted alternatives.
