Whenever i Start the engine or Accelerate over 2000RPMS i can hear this wierd vibrating noise. Sometimes its there and sometimes its not. All i know is that its coming from the outside. Does anybody else have this problem?

i dont know if its the cold. its not even cold compared to where you live. its probably around 60 in the mornings. i usually just go slower than usual until the thermometer is right in the middle. and i think the noise is coming from the exhaust

lol ya i get noise but its from my exhaust. it even gets annoying in the car (sounds like a loud *** bee) but thats the drown (spell check?) from the exhaust in my situation, not sure about yours. but you should always let your car warm before driving. let it warm until it at least hits the line. once it hits the line you can drive it but drive slow till its fully warmed up (when its in the middle).

im pretty sure its not the actual drone of the exhaust. it sounds more like something is vibrating within the exhaust than the actual exhaust itself

Do you really need to wait for your thermotere to rise if its like 20 outside and if you dont what happens?

it can be anything. usually something is loose. if you have an intake... that can be loose.. take it to any shop and get it jacked up and see if you can find where its comming from. where do you think its comming from.
