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.

Great travel pillow!
Color: White & Light Blue, Size: M - 18 x 13 Inch
This pillow is a blessing! Very comfortable, easy to fold, easy to travel with. Just finished a trip to Hawaii and so I can honestly say that I used and I highly recommend it! Ended up having to share it with my 4 year old grandson, so I will be ordering another. 😁

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.
