You'd lose. The 1000 Kitty is faster than a stock Outty 800....the Mudpro 1000, not so much.
I also have a 2011 Arctic Cat XTZ 1000 side by side, it will blow the doors off my 2012 Mud Pro 1000 - do I care -Nope.
my cats do fine, my 500 HO Polaris that I hardly use - no issues. Now my Can-Am 650 nice quad but has issues at times
but I put up with them.
Like they say Tits or tires sooner or later your going to have trouble with them
