OK,
#1, I'm only trying to help, so you can cut the A-hole attitude. I looked at your "specs" list, you say that you have ZZP headers, I know they come with a 3" downpipe, they also bolt up to the stock cat back if you select that option. Forgive me for actually looking at your signature to figure out what you're asking.
#2, the link you post goes to a U-Bend delete pipe, which is why I thought you were still confused on what you were actually looking for.
So with that, have a great day figuring this out without my help.
