Hooker Headers‘ latest Builder Series components offer the do-it-yourselfer the pieces needed to fabricate their own custom exhaust systems. If you’re the guy who has the ability to construct headers and exhaust systems in the garage by firing up the MIG or TIG welder, then you need to check these out.

Official Release:

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.
