Catless headers, but still retains midpipe cat. Ringlands are also my chief concern.

That's a good idea. I did think maybe I jumped too fast to thinking the drops were oil based on the smoke. I did swipe my hand through the drops on the ground... sure seemed oily.

Pulling the intake and checking for oil was my original plan -- and I'm still going to do that tomorrow -- but the fact that it's smoking after just sitting without being driven is making me discount the blowby theory.

Especially since this car has never had blowby issues running 20 minute track sessions... seems pretty odd that it would suddenly start having massive amounts after an autocross.
