im not sure about that car in particular but does that exaust have a braided flex toward the front?... if it does check in the corners of that typically they rust out pretty good and leaks in there also try checking the rest of the gaskets down the line.... mabe on the exaust side of the manifold
good luck

Inspect the front braided exhaust flex pipe, especially the corners where rust-through leaks are common. Also check the remaining exhaust gaskets down the line, including the exhaust side of the manifold.

Conversation Summary

The owner of a 1999 Pontiac Sunfire GT 2.4L reports a mild exhaust leak that sounds like a hard vacuum. Replacing the non-EGR manifold gasket did not stop the noise, and a lift inspection did not locate the leak. The expert suggests checking a front braided flex section for rusted corners and inspecting the remaining exhaust gaskets, including the exhaust side of the manifold.
