I've found a couple videos that show catless front pipes with Perrin catbacks and it seems like they're OK. The only two I could find seemed to have a small amount of rasp however they both had aftermarket headers and overpipes. I don't know if that increases or decreases the chances of having rasp. Seems like higher flow = more rasp, but that's just my theory.
Do you know of any videos that have a catless front pipe and Perrin catback?

As I, too, was in this same boat when I first got my car, I'll offer my experience with this car.
At the time I was looking to pull the trigger on the exhaust (June of 2012), there weren't close to as many options as we have today. I decided to go with the complete header-back system from SRT, which is now known to be among the louder exhausts (though promised to not be overly loud when I originally pre-ordered it).
As it deleted the secondary cat, it was a lot louder and also did exhibit some drone at lower engine RPMs (I forget the exact range, but it was something like 1900-2200 RPM), but I don't ever remember finding it raspy. I've since added a second resonator to the midpipe, which has helped the drone, though it is worth noting that the lack of cat means it's still much louder than stock.
As far as installation, while the overpipe was annoying, I was still able to do the whole project lying on my back with the car on 4 jack stands. I did not need to jack the engine, though I did have to remove the 2-piece OEM heatshield from the overpipe to get it out.
As far as your own situation, I'd say your most flexibility would be to go catless for now and see what you think. You can always go to any muffler shop and have them weld in a resonator if it introduces drone, or a cat to reduce volume. It's worth noting that going this route allows you to specify the exact resonator/cat that you want, and not just accept whatever comes standard on the pipe you purchase.
For example, you could go with a super low cell count cat if the noise was just a bit too loud, vs. a higher count if it was much louder than you wanted. You may spend more money when all is said and done, but the installation at a muffler shop is relatively inexpensive, and allows you to have a solution that's more catered to your individual needs.
