A few weeks ago. I noticed when starting my car there is a loud roaring noise coming from under the hood. When the car is cold and I accelerate it is very noticeable. But when the car is fully warmed up things quiet down. I had a tune up last week, and I asked the mechanic to make note of the noise. He told me nothing sounded out of the ordinary. He did mention that there was some smoke coming out of the tail pipe. I think it is the exhaust system. But I know nothing about cars. I plan on going to a mechanic and asking them to check the exhaust system. But I wanted to post here to help pinpoint what might be the problem. I don't want to get ripped off when the mechanic says the whole system needs replaced. When it maybe a loose hanger or something petty that I can fix myself.
