Product Details

The FlowTech 31170FLT long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. Constructed from sturdy and lightweight cold-rolled mild steel, these headers deliver exceptional performance with improved exhaust flow and scavenging.

Key Features:

  • High heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces underhood temps for increased performance
  • 1-5/8 inch primary tube diameter with 18-gauge mandrel-bent tubing for optimal exhaust flow
  • 3.0 inch collector diameter with 3-bolt flange attachment and collector reducers to 2.5 inches included
  • Extra-thick 0.31 inch machined header flanges with O-ring port seals for maximum sealing
  • D-port cylinder head port configuration
  • Complete installation kit includes mounting hardware, gaskets, and bolts
  • Down-swept tube design for optimal ground clearance
  • Leak-tested for maximum performance with industry-best welds for durability

FlowTech headers are designed to provide optimum exhaust flow for increased horsepower, torque, fuel economy, and improved throttle response. The silver ceramic coating provides superior rust and corrosion resistance while helping to manage underhood temperatures. Sold as a pair with everything needed for installation.

Important Note: 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.
