exhaust squeal

[KWT2000]

i have a i piched squeal on acceleration. i first thought it was the belt or tensioner but i removed the belt and went for a short drive and the noise was still there...... it sounds like its coming from the passenger side manifold and from cats on driver side. im lost any ideas????

it has the same sound as a sqealing belt though? does she do it on take off or just when she downshifts on the highway?

on take off and driving around town under 40mph once im at highway speeds it slowly goes away seems to be more noticeable in the rain. it will do it sitting just by hittin the gas quick revs to about 3000 rpm

maybe check the brake pads, could be the wear indicator rubbing on the rotor

it makes the noise while reving the engine truck doesnt have to be moving.

Exhaust manifold gasket leaking check it will have soot around gasket. I fix them all the time may also have a broken exhaust manifold stud.

pulley maybe?
