\nIn addition to unleashing the power and performance of your 4.4 Twin Turbo, our High-Flow Cats will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "punch!" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.

Good for smaller jawed dogs.
Color: Orange
This ball is so much fun for our 5 month old. He both chases it and lets it bounce in his mouth. This was after playing with it already for 10 minutes. The ball charges with a usb charger and lasts for a long time. I do take it away to keep the toy fresh and prevent him from just chewing on it. I will say the ball startles you a bit when it turns on in your hand. Happy with a different toy.

Our New Dog Sitter
Color: Orange
Our dog loves this toy so much. He just loves to chase it around. The ball has an auto bounce setting that keeps him entertained while I work at my desk. It is made of a brightly colored, high quality material and despite his rough housing it has not ripped or torn. It has a long lasting rechargeable battery for lots of doggy fun !

A hit for Border Collies
Color: Blue
Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.

Toy destroyed.
Color: Blue
Dog destroyed it the evening we received it. It was a cool toy, though. Too bad it didn’t last longer.
