Talk to me about Cadillac converters.
So my buddy just took the oil burner off his 08 diesel and is now running no muffle just a cat and strait pipes. You can tell the thing preforms much better in the driving and the MPG. Now he is talking about getting the cat off to for even better performance. I would love to take my cat off my 02 2500HD on just run a pipe to my Magnaflow muffler. My dad seems to think it is more complex on a gas then it is a diesel and I have a 8.1 liter. So what would it take to cut out my cat and not make my O2 sensors **** them self and no check engine light. A programmer?
