It seems to be of good quality for the price I like that it’s painted silver to protect it from the elements

Works good after alterations.
I was very impressed with the ease of ordering this cat. It came a week late but I understand. The pipes did not fit as hoped. Angles were off and would not connect to rear part of system. I paid a muffler shop to bend it and make it work. Now that it's installed, it seems to work fine.
