Fitment Notes
- 2WD Models Only!
- Will NOT fit 1968-1972 Camper Special gas tanks.
- Stock exhaust system will need to be modified to retain cat. converter
- 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.
- On some models with the C-6 transmission, it may be necessary to bend the linkage arm on the transmission. Bend it 1/2” to 3/4” in towards the transmission and make an adjustment at the steering column. The included instructions will provide more details on this step.
