Removing the cat will not give you any noticeable gains. I would suggest you do headers and MSD ignition first and tune that carb. Z24 has some kick.... I miss mine... but only when it was reliable, I was plaggued with carb issues the past year and other stuff started to go, so I ditched the old Z24 for a KA.
I have a vid of my 720 hauling a bike in my profile..... doing 85+ with the bike on top.
