If I'm not mistaken, which I may be, sched 40 2" pipe will actually measure closer to 2.5" on the O.D.Joshharris98xj said:Personally I would probably go with a 2.5/2.75 for a cage. After looking everywhere and not wanting to pay to have it shipped(about 200$). I checked "southern pipe" the last place I expected to have some and they ordered me some. Took about 5 days to get....can't wait to fab some stuff up.
