I have no cats, and Magnapacks...I pass inspection just fine without anyone saying anything. Oh, and it's only $12.50 for me (no emissions county).
Cops, however, have pulled me over for "an absence of mufflers." They asked me, "Where are your mufflers?" I say, "They should be right under the back seat." They stand out there for a bit, I guess to make me wait, and then they say, "I'm going to let you go with a verbal warning, but if I have to pull you over again I am going to give you a ticket for sound ordinance." This has only happened on the Baylor campus though.
I always taunt cops with my exhaust and have yet to get a ticket for it

The day is coming soon, though. I promise.
Oh! I also have 10% tint. Out of the 7 or 8 times I've been pulled over (only 2 tickets), not one of them mentioned the tint or the lack of cats.
TEXAS FTW!!!
P.S. If you're worried about a visual inspection, just get some cat shells welded around the pipe. If I had problems with inspection, I was going to do this.
