I believe it's federally mandated to have a catalytic converter installed. Technically you can get away with it if you don't have inspections, but it's still required. There are performance cats available that have a measured loss of 1 horsepower or less at the wheels. I'd look into one of those if you want a completely legal solution without losing the power and economy. --- In dmcnews@xxxxxxxxxxxxxxx, "sweetp01569" <paul.sweet@...> wrote: > > What's involved with "de-catting"?
