Had an aftermarket header with no cat on my 8th with Flashpro. When I took it to emissions out here it passed no problem and I didn't have a cat on it. Don't see why it wouldn't pass with a tune. You may just want to take it and get it checked, if you are worried about it, to see if it will pass the way it is.
I ordered the AFe carded DP so I don't have to worry about it.
