Question and comment
My question is what is the problem with exhausts on a turbocharged engine?
My comment is just a concern that the urea comments may be difficult to replace. I would hate to deal with something that needs to changed that often if it is a hassle. But urea pellets are so cheap that I cannot imangine much of a cost (urea is a form of nitrogen fertilizer that can be absorbed by trees but not by a lot of plants).
