Hey Guys. I am trying to figure out the stock exhaust size that go into my muffler. I have a 2014 F150 Stx Sport. 5.0L. I am working on getting an aftermarket muffler, 1 in 2 out. I just don't know the OD of my stock exhaust going into my stock muffler. Any experts have any input?

I think I still have the factory muffler in the backyard somewhere - if not I know for a fact the midpipe is. I can get measurements in the morning. Pretty sure its 2.75" or 3"

The exhaust is 3 different sizes. Its 3" just BEFORE what i call the ball connection, the flange with the two bolts. Just AFTER the ball connection its 2.75", at the slip joint just past the resonator its necks down to 2.5" and then goes to 2.75" into the muffler. After the muffler, its all 3".
