Exaust (CAT) question for the Cali folk

So this morning I installed my Mbrp 4" turbo back. It's the kit the re-uses the CAT.
The sound is pretty good, and my egt's did drop a little. About 75-100*. With the kit I also ordered the CAT test pipe. I didn't put it on because I'm a little worried about having it on abd getting poped with it some how.

My question is how many of you are running without CAT's? Is it worth the trouble? I would really like to run it with out the CAT I'm just a little unsure.

You'll need the cat installed when you go in for your silly diesel smog test. Once you've passed the smog, take the cat out and put your test pipe in. Reverse procedure in two years when it is time for the smog test again.
