Overview:

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.

  • Include All Mounting Hardware
  • Constructed of .049 cold roll flash mild steel tubing

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 everyday sneaker
Size: 1 Little Kid, Color: Fuchsia
I bought these for my kid and honestly didn’t expect to like them as much as I do, but they’ve been great so far. They’re lightweight, easy to get on, look cute, fit well, and actually seem comfortable enough that there’s been zero complaining (which is saying a lot). The grip on the bottom is solid, and they’ve held up really well with everyday wear, running around, playground, all of it. I also like that they’re breathable, so no sweaty feet at the end of the day. They’re not the most “fancy” sneaker out there, but for the price, the quality feels really fair. If anything, I wish they came in even more color options because we’d probably buy another pair. Overall, really good everyday shoe. If you just need something reliable, comfortable, and kid-proof, these definitely do the job.

You've Found Your Daughter's Match! Superior Sneakers for Girls!
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
Super-cute, stylish sneakers meet cushiony comfort at a very reasonable price. These sneakers have it all! The bed and sole of these sneakers provide significant shock-absorption making them ideal for serious athletics or a long day out at the theme park. Our daughter went from a Keds-type sneaker to these and she was beaming 😁! In addition to their comfort and ppearance is the fact that they fasten and unfasten with ease. Any child can put them on and take them off. The laces stretch and the Velcro is highly adjustable. Everything has been constructed with integrity. They are, also, washable so you can continue to maintain their crisp, vibrant colors and keep them looking new. They fit true-to-size and can accodimate somewhat wide feet as well. There are only positive things to say about these 5+ stars!

Nice, Tough & Comfortable!
Size: 6.5 Wide Big Kid, Color: Black
Bought as an everyday school shoe for my 10 year old son. He likes them a lot and is holding up great through rough boy play, and they still look good after a couple months now.

Pink and purple perfection
Size: 13 Little Kid, Color: Pink/Purple, Size: 13 Little Kid, Color: Pink/Purple
Fits great and perfect colors for my (not so) little. This is her first pair of "tie" shoes so we're still learning, but the laces are a good length for teaching and practicing. She says they're very comfortable too.
