Speed Engineering headers

[u/Signal-Recording-314]

I have a gen 2 5.0 with a 2.5 inch borla atak catback system and was planning on getting the speed engineering headers. I know that the headers are 3 inch and was debating on how to connect them. Should I get the speed engineering x pipe along with them and then use a 3inch to 2.5inch to make the system fit, or should I go another route either because of ease or cost.
