2000 manual 4cyl ranger. Having a problem with this rattle sound when it's coming down from a high rpm I think it's coming from under the truck. Any help will be awesome here's the video


i just went out there and hit the exhaust as hard as i could and it didnt really make any kinda of sound.
It doesnt have a cat on it anymore, just the factory muffler.
I really wish i had a tack. i was just revving it up again and it only does it when its coming down from a high rpm. It only does it for maybe a second.

 

how's your catalytic converter?
have you banged on it to see if there are moving pieces in there?

 

No cat on it anymore
Could there be pieces inside the muffler moving around? I was going to replace the muffler but I don't want the waste the money if that wont help

 

Check your motor mounts my 87 used to make that same noise.

 

Ill have to take a look at that today.
