    Gibson Headers are dyno-tuned to deliver more usable horsepower and torque at low and midrange RPM. They decrease exhaust temperature and increase an engine's ability to "breathe" (fuel economy may also improve as the engine becomes more efficient). Engineered as direct replacements for factory manifolds, Gibson Headers fit lowered or raised street and off-road vehicles.



    Features:
  • 16-Gauge Stainless Steel Tubing
  • Welding Not Required For Installation
  • 3/8'' Port Flanges (No Warping Or Leaking)
  • Quicker Response & Improved Performance
  • Cooler Operating Temperature & Longer Engine Life
  • Premium Gaskets, Hardware & OE-Style Connectors
  • Bolt-On Fit For Factory Exhaust Manifolds (Attaches To Stock Crossover Pipe)
  • 50-state Legal Using Stock Emissions Equipment (Maintains Factory Warranty & Meets EPA & CARB Standards)
  • Made In The USA!
