Check all the exhaust for the noise
Thanks Tomm.brz. I'll have a look.

I have noticed if I roll into it slow, no noise. Roll in hard, I hear it from 3500 to 4500, after that it stops. It sounds like some odd sheetmetal rattle, like maybe the tins on the exhaust or similar. My outback made similar noise due to tins on exhaust, I just got used to it after I figured out it wasn't something failing. I hate rattles, but who doesn't. It may not be a rattle, but still not sure, heard it for first time after car sat for 3 days while we went camping.

I'll chase it down, and likely change the PCV since it's a cheap check, and from what I've read, recommended anyway.

I do like that slight whistle from the SC at about 5-6k rpm though, that one should stay.
