To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% TIG-welded, the smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. It uses dual, high flow, 300 CPSI metallic catalytic converters for maximum flow providing an astonishing low end torque improvement. All components are supplied for a hassle-free installation with no modifications necessary. 100% TIG-welded by certified craftsmen for race proven strength and durability. TIG-welding provides the strongest welds reducing stress cracks. The ceramic 300 CPSI metallic catalyst is designed for maximum surface area and flow. aFe has designed this system to retain all your factory sensors for a hassle free installation. Also included are 6 O-ring header flange gaskets. Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response. These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.\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.
