I just had my DD 4 inch installed and mine does not chirp. It does make the turbo much louder and it does rumble..... got to love the rumble. You should hear it at 2500 rpm and 35 lbs of boost... it is absolutly music to my ears. I have no idea what the crickets could be... maybe a loose clamp on a hanger rubbing?? I would think if it was the turbo it would have blown up right away. I think I would crawl under the truck and check it all out. Then take it back to the shop and let them listen to it, maybe they could help. Good luck and rumble on... .
