The filter you see is new. The previous Cat filter was on there for almost a year, almost since the truck was new. I decided that since I had to replumb it, it was a good time to change it. The kit manufacturer recommended a new filter once a year. The old filter can was pretty dirty, but had no noticeable dents or marks from stones.
I had been thinking of wrapping foam around it, though, for some protection.
