These modular headers are the perfect solution for any Cayman or Boxster. Our patented RENNKRAFT™ modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use. RENNKRAFT™, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

SOUND:

Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and off throttle burbles are more robust and transparent. With the cat bypass pipes installed, you're in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn't overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car.

Great for heavy chewers! Belgian Malinois Approved!
Color: E) 8-Pack 2.5" Balls (Yellow)
I bought these 6 months ago because my dog kept loosing his Kong balls. These were such a better price ball (but still had good reviews) that I thought I would give them a try. They are wonderful. After six months of chewing and chasing and playing with a Belgian Malinois, the two that I’ve gotten out are still in great condition. The bright color makes them easier to find, so none have been permanently lost yet. They are bouncier and a little bit lighter weight compared to the Kong balls of the same size, which I honestly appreciate because my maligator likes to shoot them at my feet. So far the material seems high quality and I feel safe letting the dog chew on it for hours on end. The 8 pack was cheaper than 2 Kong balls. A great deal for a great product!!

Durable, high-bounce dog balls that hold up well to energetic play
Color: D) 4-Pack 3" Balls (Yellow)
The Chew King 3-inch rubber balls have been great for active play sessions. The rubber feels thick and durable, and the bounce is surprisingly lively compared to many standard dog balls. They’re the perfect size for medium to large dogs and are easy for dogs to carry, chase, and retrieve. After repeated games of fetch, the surface has held up well without cracking or losing its shape. One thing that stands out is how easy they are to clean. Dirt and slobber rinse off quickly, so they’re ready for the next round of play. The bright color also makes them easier to find in grass or bushes compared to darker toys. For longer life, it helps to supervise play if your dog is a very aggressive chewer, since these are designed more for fetch than constant chewing. Also, rotating toys every few days can keep dogs more engaged and extend the lifespan of each ball. Overall, this is a solid set of durable fetch balls that provide great bounce and reliable outdoor playtime fun.

toughest dog balls in the world
Color: E) 8-Pack 2.5" Balls (Yellow), Color: E) 8-Pack 2.5" Balls (Yellow)
best balls in the universe. I have a 70# pit bull and a 120# presa canaria. All the other balls I bought lasted maybe 3 weeks, I have had these for over a year and play with them and the dogs 5-6 days a week. They still look brand new, They seem like they will last a year or so and they are both serious chewers. A presa has a bite force od about 525psi, twice a pitty

They worked out great!!!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
So far have been the solution we were looking for! I was extremely tired of the non stop destruction and order of large Chuckit balls for our high energy/high drive dog. For about the same price I bought four 3 inch balls to test out their durability and fit for the thrower. THEY WORK! Perfection! They even make a fun whistling sound as they sail through the air. They do require a tad more muscle in the thrower but that is not a problem. They have already shown to be WAY more durable. The 3 inch balls work in the large chunkit thrower. Super find.

Durable
Color: E) 8-Pack 2.5" Balls (Yellow)
My dogs love them. They are very bouncy, and ideal size, and durable. Great alternative to a tennis ball which in my house only last 30 minutes.
