I think your talking about the new exhaust/cat that when it starts to get full/clog the computer will creat alot of heat in the exhaust/converter and litterally cook the soot and the puke it out like a hair ball. Now from what Ive been told by the GM guy is that this will happen every XX thousand miles. he couldnt give me any specifics on it.I asked him what if someone puts a bigger exhaust on it
(shouldnt have asked that) He said its AGAINST the Law
I then
said O K
This guy is very smart with the GM Tech line and training and very loyal to GM so I left the questions at that
