Our intakes are one-piece welded. The welds are done via a machine welding technique for a perfect bead and penetration every time. The reasoning for the welded vs. mandrel bent one piece is the lack of need for a tangent (straight section) this allows us to have the highest possible radius for our two bends, creating the highest and smoothest flow possible! These come standard in a clean, polished finished, unless a power-coating option is chosen.
