Resinator wont make any performance difference.
Cat will free up a bit of power, but nothing you wil notice.
I would reccommend keeping both.

Running without a catalytic converter is a $1000 federal fine.

Somebody at work said it's now a $10,000 fine but I doubt that.

Is a $1000 worth 1hp you won't even feel on the butt-dyno?

Is it really that loud/annoying when you get up to speed with a resonator and exhaust delete?

Also, are there any pros and cons to doing this besides sound?

It is very loud yes but for how long are you going WOT?

The biggest problem is the drone around 1800 RPM, which is roughly where you are running when on the highway, so it's a constant annoyance.
