my question would be does it seem to be more noticeable in higher/lower gears, when the engine is cold/hot, and when did it start.....

it does it hot and cold an above 4000 rpm and in every gear.

I Forgot to add that he brought up my motor mounts. He said I could have a mount bad that is causing the header to e too close to frame rail.

This is the stuff I'm talking about. That just doesn't make sense to me. Really grabbing for things at this point instead of diggin in. A motor mount on a 3 year old vehicle with 50k miles isn't very common.

I just want my truck back.
