These precision-designed, hand-crafted headers are mandrel-bent from 1-3\/4\" into 2\" heavy duty gauge .120\" wall, brushed finish 304 stainless steel tubing and are 100% hand TIG-welded for strength and durability. Optimized tube lengths deliver true pulse control technology for improved flow and performance across the power band. Laser-cut, heavy duty head flanges are machined to match the exhaust ports for a secure seal. EGT ports with plugs, quality hardware and gaskets are included to ensure hassle-free installation and quality fit.\r\nPerformance Gains: Outflows factory manifolds by up to 7%.\r\nBrushed Finish 304 Stainless Steel Construction: Constructed of brushed finish .120\" wall, 1-3\/4\" into 2\" mandrel-bent 304 stainless steel tubing for strength and durability.\r\nOptimized Tube Lengths: Tube lengths and mitered collectors are optimized for true pulse control technology which improves flow and performance across the power band.\r\nHeavy Duty Flanges: These headers incorporate laser-cut, heavy duty flanges machined to match the exhaust ports for a direct-bolt on, leak-free seal.\r\nEGT Ports: Two 1\/8\" NPT exhaust gas temperature (EGT) ports are incorporated. This allows for easy installation of sensors, gauges or testing equipment.\r\nTIG-Welded: 100% TIG-welded for strength and durability.\r\nAll aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.\u003c\/div\u003e\u003cdiv\u003eaFe 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.
