Product Details

The Gibson GP125S-C is a ceramic coated, short tube performance exhaust header engineered to replace restrictive factory cast iron exhaust manifolds. Dyno-tuned for maximum efficiency, this header is built to unlock more usable horsepower and torque in the low-to-mid RPM range where real-world street and highway driving happens most.

Constructed from 16-gauge stainless steel with 1.5-inch mandrel-bent tubing, the GP125S-C features a high-quality ceramic coating that reduces under-hood heat and helps protect the header from corrosion and thermal fatigue. The header is designed as a direct bolt-on replacement for the factory exhaust manifold, retaining the stock crossover pipe for a clean, no-hassle installation — no welding required.

Key Features:

  • Dyno-tuned design delivers increased horsepower and torque at low and mid-range RPM
  • Ceramic coated 16-gauge stainless steel construction for durability and heat resistance
  • 1.5-inch mandrel-bent tubing for improved exhaust flow
  • 3/8-inch heavy-duty laser cut port flanges — warp-resistant and leak-free
  • Direct-fit, bolt-on replacement for factory exhaust manifolds
  • Uses OEM-style connections and attaches to the stock crossover pipe
  • Compatible with lowered, raised, street, and off-road vehicles
  • Premium gaskets and all hardware included
  • 50-state street legal — meets EPA and CARB requirements
  • Will not affect the factory powertrain warranty
  • Made in the USA
  • Backed by a Lifetime Limited Warranty

The GP125S-C is a proven upgrade for truck and SUV owners looking to improve engine breathing, reduce exhaust temperatures, and gain real-world performance gains without cutting or welding.
