It's a small high flow cat. The differance in sound probably won't be much. But it is a $10,000 fine for removing a cat and not replacing it. Your state not having emissions testing has nothing to do with it.
Do it right, or don't do it at all.

I wouldn't do it personally. If you want more sound, pick up a cheap aftermarket muffler and have them weld it on. You can check with Thrush or Dynomax...both of which are pretty cheap and will give you added sound. I'm adding a Dynomax to mine.

It actually depends on your state and the location of the cat. Ths being a secondary it shouldn't cause any violation issues. Look at how many lnf guys are running catless dp. Id say try it keep the cat or even better pick up a high flow metal core cat and if you don't like it simply put one back on. I ran a 300 cell metal core vibrant on my vibe which was a 1.8 1zz Toyota motor and it made a larger difference than just the rest of the exhaust put together.

Ok the second cat is gone. After about ten miles around town it is awesome. At a steady speed or at an idle there is no noticeable noise. Under light acceleration you can here the exhaust. Under heavy throttle all I can here is the intake.
I'll post a sound clip in a little while. I think it sounds awesome. I had the resonator removed and it sounds about like I removed another resonator. I like the pop and Gargle under deceleration.

Under federal law, catalytic converters may not be removed
and replaced with "converter replacement pipes' by any person.
The 1990 Clean Air Act Amendments even prohibit private
individuals from installing "converter replacement pipes" on their
own vehicles. Anyone who installs such pipes would violate section
203(a)(3)(A) and (B) of the Clean Air Act (Act).
