Im having a trouble with a noise
you cant hear anything if the truck is idling
,its almost like a 2 loose metal part hitting against each other while accelerating or driving around 2k-3k rpm.

So I took it to the dealer 2 months ago,my service advisor test drove it with me and said he cant hear anything.

So today i decided to take it to the Mechanic friend that i have and see if he can figure out what it is ,He test drove it with me for couple minutes and he said its Catalytic Converter.
So any of you guys had the same trouble before ?
Or any thoughts ?

under the engine somewhere but like i said it doesnt make a noise while idling so its hard to figure it out.
