Anyone remove the catalyst from a Cat C-7?

[Longroad]

I noticed that my new to me RV has a catalyst exhaust, I was just wondering if anyone has ever removed one a replaced it with a standard exhaust. It is a 2005 C-7 350hp. I noticed that the thing must have gotten hot at one point since the adjacent basement storage has melted carpet. I have placed some heat shielding there, but maybe removal of the catalyst may make that problem a thing of the past and maybe even let the engine breath a little better.
Thanks

you may need someone to adjust the computer, to get the truck to run properly if it's removed...
if you are required to have emission testing, it will fail the visual test..
and i would defiantly have a heat shield installed between that pipe and the floor of the vehicle, including the storage areas.. it's not a pleasant thing to have your trip spoiled due to a fire...
