aFe Power Twisted Steel Headers | 2019-2020 Chevrolet Silverado/Sierra (48-34134)
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.
