Hooker Headers New Builder Series is designed to help header fabricators build their own custom exhaust systems. For GM LS engines, Hooker offers both 3/8” mild steel and investment cast stainless steel warp-resistant flanges. Proprietary 304 stainless steel merge collector with Hooker’s revolutionary internal attenuation spear is perfect for not only LS engine builders but a wide range of engine applications.  Other key components include Hooker’s innovative 304 stainless steel stamped X-crossover assembles for both 2.5” and 3” tubing styles that provide easy fitment and X-crossover performance into any system with a limited amount of system modification. As an added benefit, these stamped crossovers permit multiple inlet/outlet leg routing to be fabricated (parallel, splayed or hybrid) without having to modify the stamping. To aid in the fitment of hand-built systems, fabricators will appreciate the ½” diameter 304 rust resistant stainless steel, barbed hanger rods in two and 10 packs, compatible ½” rubber isolators and 2.5” and 3” stainless steel band clamps to ensure a tight, leak-free seal.
