aFe Twisted Steel Headers
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. Order the style and configuration tailored to your vehicle and engine application.
