Flowtech Headers are the perfect combination of quality and value. Flowtech is proud to announce the release of a complete line-up of Lakester headers for Big Block Chevy motor. These headers are a throwback to the dry lake or salt lake racers from the golden age of hot rods. These Lake style headers are a great way to build power and have the retro hot rod style.
Features:
  • Perfect header for vintage lake-style rods. Taken from the classic Lakester rods from the early dry lake and Bonneville speed racers
  • High flow, mandrel-bent tubes provide consistent tubing diameters for smooth flow and increased exhaust velocity
  • Heavy duty tubing and high quality welds for increased strength and durability
  • Smooth transition, 1-3/4 inch diameter primary tubes are used for increased exhaust flow increasing performance, improving throttle response and broadening the torque curve
  • Long transition velocity collector connects to an undercar exhaust or the block off plate can be removed for maximum sound output
  • TIG-welded, machined 3/8 inch header flange for a leak-free seal and maximum strength
  • Premium aluminum header gaskets and installation hardware included
  • Coated in polished silver metallic ceramic coating for maximum corrosion resistance, an aggressive look and reduced skin temperatures

Specifications:
  • Collector Diameter: 4 inch
  • Flange Size: 3/8 Inch
  • Header Finish: Silver Metallic Ceramic
  • Header Style: Lakester
  • Primary Tube Dia.: 1-3/4 inch
  • Tube Material: Mild Steel

Manufacturer Part Number : 11703-1FLT

Part Notes:

Big Block Chevy Lakester Header; 1-3/4 inch Primaries, 4 inch collector, and 3/8 inch Header Flange; Silver Metallic Ceramic Coated Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.
