Sometimes noises can be notoriously difficult to diagnose. Be a detective; try to pinpoint the noise. If you don't notice a difference in driveability, such as loss of power, misfires, or strange/different transmission shifting patterns, I would begin underneath the vehicle. Safely raise the vehicle and check exhaust hangers and catalytic converter heat shields. Use a rubber mallet to bang on the exhaust to see if you can duplicate the noise. Be safe! Be sure to do this when the vehicle is cool, and be absolutely sure the the vehicle is properly supported.
