V10, no power.

Glad it was simple. I was quite sure it was the Cat from what you described.

X2 although some of the other suggestions are valid with the same results in loss of power,

Glad you got it running right again.

Thanks. It all makes sense to me now. The sounds would change due to the broken pieces of ceramic moving around. While it was still running okay, I would look around for a loose heat shield and there are alot of them on this truck. I never had a catalytic converter go bad before.

Being on a fixed budget, I am just glad I don't have to deal with emission testing especially for the limited amount of miles I actually put on the truck.
