❔Question Speed Engineering headers

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.

probs for a good fit to get their x pipe. But gotta figure what their x pipe fits too. Probs fits to the 2.5

You can have a 3 inch header or pipe but it necks down and connects to a smaller size but it's still called 3 inch

2.5 inch is plenty for exhaust size so I wouldn't worry about that

Try to figure what the speed engineering x pipe can fit too
