Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces underhood temps for increased performance.

  • Tuned-length primary tubes for street performance
  • Mandrel-bent tubing for smooth exhaust flow
  • Light weight & sturdy 16 gauge tubing
  • Mandrel-formed Power Plenum collector for low back pressure
  • Sturdy, leak-tested O-Ring port seals
  • Engineered for a precision fit
  • Designed for easy, trouble-free installation
  • Includes all mounting hardware and premium gaskets
  • Works with air conditioning, automatic and manual transmissions with floor shifters
