Depends really. On my 550, I put it out where it can get air.....keep it cool, and it will love you for it.
If you have a leftover bracket mount it there, and then paint, polish or detail it so it looks good to the eye.
I had a front side plate bracket still on the frame on the left/chain side. I mounted by rec. there. Then buffed it with steel wool. Looks good to me!
