    All 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). Designed as direct replacements for factory manifolds, Gibson Headers fit lowered or raised street and off-road vehicles.

    Features:
  • Chrome-Plated 14-Gauge Steel
  • 3/8'' Port Flanges (No Warping Or Leaking)
  • Cooler Operating Temperature & Longer Engine Life
  • Premium Gaskets, Hardware & OE-Style Connectors
  • Bolt-On Fit For Factory Exhaust Manifolds Using Stock Crossover Pipe
  • More Usable Horsepower & Torque For Quicker Response & Improved Performance
  • 50-State Legal Using Stock Emissions Equipment (Maintains Factory Warranty & Meets EPA & CARB Standards)
  • Made In The USA!
