I might be going nuts but when i'm in my truck driving down the road theres this noise it sounds like the motor is going to fly apart. But when i'm sitting still and slowly rev the motor its quiet. Now i was wondering if it could be in the trans or maybe the torque converter or something. The strange thing is i don't remmember this making this noise before i but the new exhaust on. Is it possible that its just a different sound from the exhaust thats making me think theres a noise? Did this ever happen to anyone else.

You say the noise started after new exhaust was put on? Is the pipe hitting the cab or frame anywhere? Are the motor mounts good? If they're loose the engine could be shifting around causing problems.
Just my $.02
