Outlet size of Standard p38 Exhaust

[Chad]

Can anyone tell me the Outlet size, of the collector/flange of the the p38 headers?

Just organising an exhaust for a Project, trying to get all the bends, and stuff ready.

Pretty sure its 2.5", but don't have mine here to measure yet.

Thanks Chad

Where the headers connect to the downpipes? If so, 2.5 inches OD. I just measured a spare down Y-pipe in the garage.
