Fitment Notes:
- Pontiac V8 Engines Only!
- Will not fit Firebird/Trans Ams with column shifted standard transmission.
- Must modify stock exhaust to retain catalytic converters.
- Will not fit Ram Air vehicles.
- End holes on head must be drilled and tapped to ensure proper seal.
- 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 recommend 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.

Great purchase! Will Buy Again.
Color: A01-Colorful Pink
Best purchase for my childs tablet. They are able to carry it like a cross-body with the strap or hold it with the handle. The handle is able to rotate in different directions to set up hands free on a table either longer way (landscape) or short (portrait). It has a hard case then the thicker silicone surrounding it. It does a great job protecting the tablet. My little one has dropped it plenty of times and it's still in great condition.

So far, indestructible.
Color: Coral Orange
Such a good case! For a 6 year old that isn’t exactly gentle with devices, it’s perfect. The swivel kick stand is pretty versatile, easy to find a comfortable angle to see the screen no matter which weird position your kid sits in. The color is really nice, the orange is soft and very pretty.

Sturdy just wish it could be adjusted to hang shorter
Color: A01-Colorful Pink
Very sturdy. Love the colors, easy for my 4 yr old to handle and use.
Wish the length could be adjusted shorter for her though. When wearing, it tends to hang low by her knees.

Very reliable, even after 1 year!
Color: A01-Colorful Pink
I purchased this over a year ago. It has since been dropped, stood on and thrown (all by toddlers) and no visible damage whatsoever! I love the kickstand that also double has a way to hold while moving. It's a bit complicated to initially put together, just because of all the placement of the silicone around the plastic box, but once every bit is in the right place you're golden. I also appreciate the port cover to add an even higher durability rating from me. My toddlers find this very easy to use and I love how versatile it all is. Definitely worth the money to keep the iPads running and protected.
