Yes, I still have them. They were on my wife's car. I liked the sound; she didn't. She wants a deeper sound. The sound level is louder-than-stock, but not as loud as Corsa-brand, Borla-brand, or Flowmaster Outlaws and these are legal in all states. With just 2000 miles of use, they are almost new. The mufflers are boxed and ready to ship.
