Twisted Steel Performance Headers for 2019 - 2020 Chevrolet Silverado / GMC Sierra by aFe Power

These aFe Twisted Steel headers are constructed of 409 stainless steel tubing with thick, CNC-machined flanges to ensure a leak-free seal. They incorporate a merge collector design, reducing the turbulence that occurs when using the traditional form collector-style designs. The performance gains are obvious when coupled with a high-flow Y-pipe. The aFe headers feature a tuned length primary that is out-flowing the stock manifolds by as much as 46 percent.


  • 1-3/4" Mandrel-Bent 304 Stainless Steel Tubing for Unrestricted Flow
  • Optimized Tube Length Pulse Control Technology Delivers Improved Flow and Performance
  • 4-to-1 Mitered Merge Collectors Decrease Turbulence and Increase Exhaust Velocity
