This is what mine looked like after a couple of weeks of not washing it.

 

when did you get a Berlina?

 

Yep, I spit soot all over my garage floor.

 

I have Krank vents, an oil catch can, and a quality tune and am still getting a fair amount of "soot" coming out my exhaust. I put some plastic visquin (spelling?) behind my car to help prevent the soot from getting all over my garage. I've just come to accept it.
