I have a an exhaust leak sound that is coming from what sounds to be my mid pipes. I've had it on the rack and it still sounds like its coming from the mid pipe. I've checked every where and i can't find any leaks or anything loose. It is the worst when its cold. When it warms up it get better, and then when it gets hot it goes away. Any ideas

 

I have a slight exhaust noise to from my truck that is only apperent with light acceleration. It wa sone my truck since it was new. Mine is really faint so I neve botherd to fix it. The only thing I did was check my plugs to make sure it was not a plug about to launch. Even though my noise was coning from the mid pipe as well I still checked the plugs just in case

 

mine started very faint under light accel too. Then it got worse. and now it has leveled off. its driving me crazy.
