A few months ago my car started to make this extremely annoying rattling noise when accelerating. The thing is it's only noticeable at exactly 1500RPMs. I can recreate the sound only when the car is in gear and I rev it the engine with foot on brake to 1500RPMS. It's been driving me nuts. I even replaced 2 exhaust gussets in a Nissan TSB but it still did not fix the problem. It's definitely sounds like it's coming from the exhaust. A while back I had heat shields removed because they would rattle during a cold start. Nothing is loose, exhaust shop had it checked out and even I went under the car myself. Something must be inside the exhaust.
