Have GMMG, thinking of Corsa.....
I have the Corsa system and it is pretty quiet just cruising around. You won't draw any unwatned attention. If you go above 3-4k withi it the thing opens up. I've done basically bolt-ons with ORP and CATS and I used to just use the cats or if I wasn't feeling lazy I'd swap em in / out for inspection. I have probably been pretty lucky but I don't really have any drone.
Now that I got the H/C it is a bit different. No matter what the car is louder and more aggressive sounding so I said F'it and just leave the ORP's in to let it breath as much as possible. I don't daily drive it but do take it out when it is nice out. No real drone still when riding around but the lope at idle is noticable.
Right click / save as for a clip of the Corsa
I got this back in 2000 and am on my second muffler. The first one had a weld break loose or something and sounded like hell. They fixed it but I am pretty sure I had to pay shipping for the new muffler (or at least to send my old one back) . No issues 2 years later with the new one.

My Corsa has NO drone. LTs, High flow cats, Corsa Catback.
As far as your question about mufflers....year and a half and still on my first and only muffler.
I have corsa with FLP LT's and gutted cats. I think it sounds awsome. No drone with a little rasp. It's perfect for cruzin around. When I want to get some attention I open up my electric cutout and then it just sounds mean. I'm suprized that its actually deeper with the cutout open but it might just be cause its way louder. I have short sound clips of both if your interested. I can't post them cause I don't have a host. If someone wants to post them for me I could email them or if you want me to just email them to you let me know.

Keep what you have you already spent the money on your setup. Install the Borla XR1 and you will never look back at the drone or cats. High flo cats do not rob that much power but they did take some of my road clearance. With the ORY I have no issues and if I wanted to drop the car I could now. I also think the GMMG sounds better I had the Corsa first then bought the GMMG.
You need to get in contact with this guy. Hw wants to trade Corsa for GMMG.
