I have a 2007 M1151A1 which has had a chronic problem of spitting soot and when hard accelerating will trail a thin stream of black smoke. I am also of the opinion that it is somewhat overly anemic in power output. Also, I have never been able to hear an audible turbo "whine" even with aggressive throttle changes. So, after reading up on possible causes, I decided to pull the catalytic converter to gauge it's condition. I am assuming the black is soot and the grey is carbon deposits (?). So, is this a "gunked up" or clogged cat? I was only able to take pics of the discharge end of the cat. I tried to insert a flashlight into the forward end but was unable to see any light through the medium. If needing cleaning, does anyone have any proven suggestions other than what I've seen on youtube?
