Collector size on BBK Long-tube header?

[Aftrbrnr]

I've looked on their website and several other websites, but I can't find out the size of the collector. I want to find out so I can take the first step to see if they'll match up with a Pro-Chamber, does anyone else know?

I assume they come with either 2.5" or 3" collector. Most other headers do.

2 1/2 ball socket. I don't know about the pro chamber.

Yeah, I swear with LTs and a Prochamber, you must buy MAC Headers.
