Oil spitting out of exhaust at idle
Alright... so here's my story.
I just today bought an 06 Cobalt SS with a 2.8" pully, 60# injectors, and its stage is 3 ZZP. It has a catless downpipe. It has 139,000 miles. It runs really well so far, the tranny is solid, everything is solid on it and I put about 150 miles on it today.
I get out in my garage and I'm working on it and it's idling for about 5-10 minutes when I notice it starts spitting oil in specs on the floor and straight out of the exhaust. It's a sizable amount, certainly concerned me greatly.
The car idles fine and doesn't seem to have any issues. My girlfriend said that she saw white smoke coming out of the exhaust when I got on it when she was driving behind me in my other car on the way back from the purchase.
Don't tell me I have piston issues... is this possibly a tune problem? I don't have much supercharger knowledge. Any help is greatly appreciated.

Yeah it's definitely oil. I put my hand over the exhaust and it gets oil spots all over my hand and oil spots all over the garage floor. Like you can see it spitting out when it gets bad.

This exactly, if your engine were spitting oil out the exhaust, it'd have a blue cloud following it and you'd be out of oil by now.

My guess is that the guy that had it before me didn't stomp it at all, and I wasn't by any means redlining it, but I was certainly getting on it, and that caused a bunch of excess buildup to get released and mixed with the water coming out of the exhaust.
But when looking at the motor after driving for a while, I notice a small amount of oil around the top of the spark plugs, this is what originally made me believe it was oil in the exhaust.
I do appreciate all the feedback guys. I've never owned a car like this so a lot of this is new to me.
