Oh, While we're on this subject (what's this we, do I have a mouse in my pocket?) I had a fairly major obstruction in my exhaust last week. After some careful detective work, I found it was only a Cobalt ss that got sucked in through my turbo. I will give credit where credit is due though, he didn't get COMPLETELY spit out through my exhaust. I had to pull him out with a pair of hemostats. Honestly though, it was harder to clean the carbon buildup from my exhaust tips.
