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 better 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

  • Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street

WARNING: It is against the law to install this part on an Emissions Controlled Vehicle

Will not fit with Powerglide transmissions on Chevelles. Engine Swap Applications: 1973-1981 Camaro; 1975-1977 El Camino; 1975-1977 Chevelle; 1970-1981 Firebird/TA 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. Please call Flowtech tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. 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.
