Strange rattle only upon acceleration

I have a strange inconsistent rattle coming from under my 2000 ranger when i shift into 4th and 5th gear. The noise is only while im accelerating it stops at cruising speed. It almost sounds as if something is being blown around inside my exhaust system. Theres also a little bit of a rough idle which i originally suspected to be due to the coil packs needing to be replaced but im starting to think it could have something to do with this rattle. Ive already cleaned my MAF sensor and IAC valve. Im going to drive myself crazy trying to get to the bottom of this noise i dont know where else to look.

Yup ron got it haha.

Cat could be broken up inside - sounds like a coffee can full of rocks. heat shields can rattle - sounds like peagravel on a cookie sheet. Muffler interior baffles can break spotwelds/rust off and sound like someone shaking a stick in a tin can full of rocks.

Once you figure out what it is my analogies will make perfect sense haha.

Mine was an exhaust hanger rusted through and broke but was still laying against the exhaust so it would create a heck of a rattle.

did you also do the muffler and cats? See if you can grab the tailpipe and push in and out and really shake the exhaust.

Sounds like the rattle is when the load is high. Could be exhaust but could also be spark knock.
You might try filling w/93 octane once. If it goes away then you'll know it's not exhaust. (easy and cheap thing to test)

Sounds like a bad motor or transmission mount to me.

iI've had a tranny tailshaft mount cause noise before. The rubber was broke down due to age and the metal encased in the rubber was touching. Although it made noise only when engine / tranny shake happened. Like when slipping a clutch too aggressively and the rpms go to low.
