I would check motor mounts. If the engine torques too much it can stress the exhaust.Crude mock up for reference. Recently replaced the entire exhaust (minus the manifold) as the old one just now fell to pieces. The old pipe broke in this spot once. Had it welded and all was fine for a whole 6 months. Broke again, had it repaired again. Fast fwd to the brand new exhaust. This same pipe broke in a measly 2 weeks after install. What gives??
However, that said, there should be a flex pipe in the exhaust closer to the exhaust manifold.
If someone. . . a shop . . previous owner(?). .. .. "repaired." an exhaust problem by welding in a standard pipe. . . then no flex.
But i would check motor mounts too. Have someone on the cab with engine running, Set parking brake on full . . . also have them apply the foot brake hard. Place gear selector in Drive
. . Then pop the hood . .. stand off to one side. . left or right fender and see if the engine moves up and down more than just a little.
