No cat will help lower your EGT's especially when towing. Also it will help with carbon build up in the exhaust. But one thing if you idle alot, you will loose a bit of heat in the exhaust. Also some states will get you if you have emission inspections.

I guess I would evaluate what I use the truck for. I have not cat on mine and it runs great, but I run tuned and tow alot with my truck.

Hell yeah lose the kitty, sounds like a C17 taxing on the run way..... Just hold on to it just in case for warranty issues
