Default MSD 2Step VS Catalytic converter?

Not sure if this is the correct section so move it if need be. My question is, If I install the plug and play MSD 2 step on my Firehawk, would it ruin my Cats? I heard that when activated the unburnt fuel will kill the cats. Any truth to this?

A good chance they'll get "toasted". Eventually, the brick will be either melted, or melted and blown into chunks....

Make a y pipe that you can swap out with lots of cats in it. Use v-band clamps or slip connectors to make it quick and simple to swap from "off road" to "street" ;-)
