Our LS header flanges are CNC machined from 304 stainless steel to eliminate distortion and ensure a flat mating surface. They're 3/8" thick with a machined contoured surface that looks more ascetically pleasing than other generic header flanges on the market. The ports are machined to accept 1 7/8" primary tubing with an internal stepped bore to provide proper tube depth.
