    weird noise on start up

    I have a 2002 Z28. every so often when I start it, it runs for a few seconds then starts to make a loud whining noise from the left front behind the headlight. Also if you go to the back of the car the sound also seems to be comming out the exhaust too. I was thinking maybe the air pump cause after about 5 minutes of running the noise goes away the same time the air pump shuts off. any thoughts would be great.
