Thought I would post this here as it is strictly a cosmetic mod.
Found these on Amazon:

I like these because they have a factory look to them.
I was able to get these pushed on so the tip of the exhaust pipes tucked nicely into the edge of the sleeves, but it took some moderate cutting on the two inside tips (the tips closes to the hitch). I cut 1/4" off of the back end of 2 sleeves so it would clear a bend in the pipe.
Others have installed them as well and are saying they were able to just push them on, but not sure they are getting the edges tucked into the rim or not.
Anyway, price is right and I like the results. They have been on for a few months now with no issues.
Here is a thread with some other options. Thanks to ninefourteener for doing the research on the dimensions needed.
