I know the cats are at the forward edge of the can where the header pipes start to widen. Can the cats be removed without cutting the can? Or ae thy too far back?

If you do as Mellow suggested, you may want to keep the OEM exhaust until after your next inspection just in case it won't pass inspection in NJ with non-stock exhaust. Keep in mind that replacing the exhaust cans may violate EPA requirements that specify noise emissions of not more than 80 dBA. It says so right in the mufflers. I don't know about this point, but some states may fail motorcycles that have any aftermarket exhaust systems.
....I don't remember a bike routine inspection.

Good point, here in Texas they just say 'sounds nice, here's your sticker' lol
I would leave them alone. The OEM mufflers and cats are there for the environment and to provide performance for the engine. There is a certain amount of backpressure attributed too the cats, this is taken into account with the programming of the ECU. Removing the cats and decreasing the backpressure can actually decrease the low end torque. FI bikes come lean anyway, from the factory, to meet EPA regs.I know the cats are at the forward edge of the can where the header pipes start to widen.

NJ does not have bike inspections anymore. In my opinion a dumb idea, I like to know that rat bike pulling up to the light behind me has working brakes.
Thanks for the replies! To address a couple of things... NJ does not have bike inspections anymore. In my opinion a dumb idea, I like to know that rat bike pulling up to the light behind me has working brakes. I was thinking of trying a fuel controller, which would richen things up a bit. So removing the cats would add exhaust flow, they don't change direction of the exhaust scavenging like the baffles do. That paired with a K&N filter would help it breathe. And it wouldn't affect the sound because all the sound baffles are after the cats. I don't want aftermarket, I like the stealthy sound. These are just some ideas I've been bouncing around in my head.
I think FI doesn't care about back pressure.
