Ok so I've tried asking this a couple times in the problems forum but can't seem to get an answer.
I've recently noticed that my exhaust has been a grey color instead of the jet black it was when I originally did my dpf delete. What could be causing this and is it a problem in the making??
I will say that I live in alberta Canada and the temp the last several weeks has started to drop for winter. Could temp be the culprit??
