I'm tired of these weird noises..

alright so ive had my car for a year now, and everytime i start it up in the morning (cold start) it makes a loooooooud rattling noise at first, then it makes another rattle when the other exhaust kicks in. anyway ive read and researched that it could possibly be normal, but ive also read that its the wastegates, i talked to my service advisor a while back, he said its normal and wouldnt believe me, another thing noise i noticed today was when i have the air blowing and i turn my steering wheel to the left i hear like a high pitch chirping noise. any ideas? let me know please thanks! I have an oil change appointment this thursday i was thinking of making a video of the rattle on cold start and showing it to the mechanic. belows a video i found on youtube of the similar problem i have, the guy had his wastegates replaced and his left exhaust..
