What is the cause of this noise. Ive only had the car for two months. Also, the mufflers sound like that are choking at first start up. Can someone help with these start up noise issues.

EnthusiastYou have 2 things happening on startup! An Airpump for the emissions system is turning on and also a high speed fan that sounds like an airplane is ready to take of is also coming on! That is a normal operation !!!
