My engine is loud on my 2005 Buick Rendezvous. It's ok until I get into 2nd gear (about 10 mph). Doesn't seem to be an exhaust manifold problem as far as I can tell. One other thing I've found (I'm not sure if this is a real symptom and related or not) is that when I'm in park and rev the engine, the engine will go to 4000 rpms, and then drop down to 3000, and cycle back and forth between those 2 points if I'm holding the accelerator down.
have the same problem?
