Right, I don't hear a metal to metal sound, still works. Suggest a video taken moving around the engine bay with someone reving the engine. Hard to identify the sound from the cabin. Does the engine rev normally and hold a steady RPM at say 2500?
Since it wasn't there before your work and was there directly after your work and you didn't disconnect/loosen any of the exhaust system my guess is it is associated with the work you did.
