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.

Nice appearance, lacks sturdiness in the long run
Color: Raven
Decent quality on the surface, but likely to eventually break down with aggressive tuggers or strong jawed dogs. Best for medium drive pups at best.

Color: Raven

Excellent quality, larger than expected, machine washable
Color: Magnolia, Color: Magnolia
It's my fault for not realizing this toy is almost as long as my 7lbs papillon lol. He is not sure what to do with it right now but having a good time trying to figure it out. I thought he and his sister would love to play with it together, but it's much firmer than I expected. This is great news for larger dogs!
It is a great quality toy. It's ethically made with recycled materials by a company in Colorado and manufactured in Vietnam. It's machine washable. It's a good value and should last for a long time (even with larger dogs). It's not too heavy, but due to its size, it may not be the greatest choice for toy dogs or small puppies. Oh, and it's bright colors and pattern look awesome.
My little guy is an aggressive chewer for his size and is quite toy protective, so he has already claimed this as HIS as I'm writing this. He is having fun scratching the material it's made of, chewing it, rolling around with it, carrying it around, and keeping it away from his sister (also a papillon). So, we're happy over here.
