Have a peculiar noise from under the truck after i shift.

Hard to explain but kinda sounds like a steel housing&shot maracca just after shifting, letting the clutch out and accelerating for about 1-2 seconds.

Almost like tin vibrating against metal i suppose. Could this be the clutch?

I notice NO slippage or anything like that.

 

Any chance the exhaust is rubbing somewhere?

 

Hmm, possibly. I was paying closer attention yesterday and it seems to be coming from the rear pass side, so tailpipe rubbing is possible or maybe tailgate? I will check into it alittle more tonight.
