Description

Flowtech Headers are designed for performance and value. These "4 to 1" LS Turbo headers are available in 1-3/4" and 1-7/8" tube diameters, providing a compact package suitable for various universal fit turbo header configurations (Up and Forward, Down and Forward, or Down and Back). They feature CNC Mandrel-bent tubes for consistent diameters, smooth flow, increased cylinder scavenging, and improved engine breathing. Constructed from heavy-duty 16-gauge 304SS (Polished Finish Only) and 409SS (Natural, Black Painted, and Ceramic Coated finishes) tubing for strength and durability. They also include a 3” collector for maximum strength and exhaust flow, a 7/16” thick header flange for a leak-free seal, premium aluminum header gaskets, and 3” V-Band Flanges and Clamps. Available in Natural, Black Painted, Ceramic Coated, and Polished finishes.
