Default 5.3 exhaust size
Anyone got a 5.3 manifold with a short piece of pipe on it? I need to know the exhaust pipe OD. I need to pick up and elbow when I get off of work today and forgot to measure mine.

My 2002 4.8 has 2 1/2" pipe right at the flange.

I found a couple of posts, on other boards, that said the 5.3 has 2 3/4 OD pipe. I decided to wait and measure mine.
