I would go with the chrome Fatcat (I think they are cheaper than the black) and have it Jet-Hot coated Gloss Black before you ever put it on. It is going to cost around $250 more for the Jet-Hot, but it is good up to 1100 degrees.
I'm not sure if the heat shields are removable on the Fatcat. If they are, just Jet-Hot coat the shields and save yourself some cash. I think you would really like it.
Either go chrome or black it all out.You have a nice balance right now.I think if You go black,it will look a bit unbalanced but what the hell do I know.
I take it back. I never looked at all the detail chrome you added to your engine. Go with a chrome pipe and Jet-Hot the muffler only gloss black. That would look sweet IMO.
