Product Details

The FlowTech Exhaust 31100FLT Long Tube Header delivers enhanced exhaust flow and performance gains through precision-engineered design. Featuring a ceramic coated finish for superior heat resistance and corrosion protection, this header is built with lightweight yet durable 16-gauge mandrel-bent tubing that maintains consistent diameter throughout for optimal exhaust velocity.

Key Features:

  • 1-5/8 inch primary tube diameter with 3.0 inch collector outlet for improved exhaust scavenging
  • Tuned-length primary tubes engineered to maximize low-end torque and top-end horsepower
  • Mandrel-formed Power Plenum collector design reduces backpressure and turbulence
  • High-temperature ceramic coating protects against rust and lowers underhood temperatures
  • Leak-tested O-ring port seals ensure reliable gasket-free connections
  • Complete hardware kit included with premium gaskets for straightforward installation
  • Engineered for precision fitment without interference to factory power steering or brake components

This long tube header is designed for enthusiasts seeking measurable performance improvements with easy bolt-on installation. The mandrel-bent construction eliminates restrictive crimps found in crush-bent alternatives, while the tuned primary tube lengths optimize exhaust pulse timing for better cylinder scavenging across the RPM range.
