Oil leaking from exhuast

[adamc44]

I just had a shop put on an mbrp exhaust on my 03 with a 7.3. It prob doesn't have 20 miles on it. Well I was cheacking out the shiny tailpipe when I noticed oil running out the exhaust. I'm not sure where to start. I've read it could be o rings on the turbo or a Pcv valve. If anyone can give me some guidance on where to start checking to determine the problem, it would be greatly appreciated. Should I still start or drive it?

The exhaust system may just have residual oil in it from the mandrel-bending operations during manufacture. Give it some time and see if the oil goes away.
