Sounds like it's dragging on a tire or other rotating part.

Have ya actually crawled under it and looked for rub marks yet?

I work at a body shop and we have had it on the lift the past 2 days trying to find out what it is. We made sure that there was nothing rubbin on grinding anywhere and we THOUGHT that everything was fixed but obviously not

Maybe it's a loose part vibrating?

(I spent 1/2 day at Mufflex while they diagnosed a weird high-pitch "grind" type noise at certain engine RPMs, turned out to be a plate on the exterior of the muffler had popped a weld)

Did you check over the k-member really well? Thats where my pacesetters were rubbing. Everytime you took off it would rub and make a grinding like noise as the header scraped agaisnt it.

Even when you have it on the lift, that doesn't mean that when it is settled on the ground it wouldn't rub. Did you test it running when on the lift?

yes we tested it on the lift. The only time you can hear it is when you actually drive the car. Thats what is so confusing to me ...

Sounds like the y-pipe is rubbing when the engine torques over under acceleration. No way to reproduce this on a lift.

(thank ya, thank ya very much)

If metal is rubbing, there's a shiny spot somewhere waiting for you to find it.

Or, just loosen up all the joints in the exhaust system and push the pipes way far away from any nearby body/chassis components.
