| Description | The exhaust system for WRX STI / S4 owners seeking to extract even more performance from their car. The system is built around the muffler installed as standard on the limited edition STI S207, and has been tuned specifically for the base WRX STI. Back pressure is more than 40% lower to deliver much quicker engine response, which translates to noticeably faster acceleration from standstill or when powering out of low-speed corners. Featuring twin 101.6 mm diameter angled tips for a classy yet powerful looking rear, the entire system has been exclusively tuned by STI for optimum engine performance and reliability. Particular attention has been paid to the exhaust tone, which has been tuned to deliver a refined, soothing sound to suit the WRX STI / S4. |

Squeaks break immediately
Color: 12 Tennis Ball
Squeaks break almost immediately, even with very light chewing. Some are so badly made that the squeaks break after one or two squeezes. Get Kong balls instead.

Nice balls but arrived with a bad chemical smell
Color: 12 Tennis Ball
Wonderful Product!!! The balls themselves are amazing and the squeaker in them my dog loves.
I am giving them only a three star because they arrived and they SMELL like chemicals so bad!!! I was afraid to give it to my dog so i washed one out and put it up hoping the chemical smell will go away. This not good for a dog as unknown chemicals can make them really sick. Whatever amazon is spraying on their stuff it's not good

Puppy tested & approved
Color: 12 Tennis Ball
I ordered these squeaky tennis balls for my cocker spaniel. She absolutely loves these tennis balls with the squeakers in them! She plays with them all day, and chews on them frequently. We have not had any problems with her, breaking the tennis balls, which is generally the issue we have with her. The tennis ball fuzz stays on the ball very well, which is usually an issue with standard tennis balls, because my dog likes to peel off the yellow fuzz on all tennis balls. She has not been able to do that with these. I will definitely be buying these again , but will not need to anytime soon as these are extremely well built.
