Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Rusty LOVES them.
Size: Large
Our dog loves these balls! I like that they squeak and the texture prevents them from getting slimy from his spit. They last more than smooth balls. You do need to make sure you get the right size for your dogs mouth.

Squeaker Does NOT Break in a Day
Size: Large
My mid-size, 40lb heeler mix loves these chew balls. They are easily his favorite toys to fetch, chase and chew on. We’ve had the chew balls for several months, and, unfortunately the squeaker does not break in a day. They are still going strong. Extremely durable and great value for the money.

Very durable, even after the squeaker quits
Size: Large
These balls are really durable! The squeaker inside only lasted about a week, but my dog loves to chase it and just chew on it in his mouth. I took two of them to the dog park, and the other dogs were the same way with them.
