I went through three sets of ceramic - they are challenged for everday driving. Rocks and road junk beat them. Then there is the ability to clean in between the pipes.
So, we moved to steel pipes ( stainless if I could have had them made ) and painted them black. They get just as beat up, but I glass bead them and paint them blackl again.
You need to determine what you are goigng to do with your car. If you are driving regular, you may grow tired of polishing again and again to maintain appearance. If you are going to build a trailer queen, polish and chrome may be your preference.
Just my $.03 worth.
