In terms of flow, the Corsa resonator is the same as any 2.5" resonator.
As for sound, it removes all rasp and drone.
The only data I have for that is when I went from the stock catback with gmpp touring muffler welded on to the Corsa Touring catback. While the stock catback sounded nice w/ the gmpp touring muffler it droned on the highway a bit. When I bolted on the Corsa, I couldnt believe how quiet it was while cruising. You can barely hear the exhaust inside the car at a 75mph cruise.

If you want something that is none restrictive and is quite then modify the stock cat back like I mentioned.
ZZP Cat'd LT will free up the restrictions where it matters the most.
Cut off the 2" inlet to the resonator and replace it with a 2.5" or even a 3" flange if you want to run a 3" outlet from your DP. Then run the stock muffler.
That might be just a touch restrictive but it will be quite. I am sure it will be fine for any size pulley you plan on running on the M62. If you don't think it is, then replace the stock muffler with a 2.25" Stainless works turbo chambered muffler.
Part number and/or where to buy it...

Well going back to the first page, riceburner... you were right it does sound ***tty. Retightened everything and put a new gasket in today and got rid of my leak(I think). It sounds better since I got rid of the leak, but after 3 grand it sounds sooo ricey. Haha oh well its a supercharged 4 cylinder... not much you can do.

No problem man!
Let me know how you make out.
Just for ***** n' giggles.... install the stock downpipe (if you have it). This way you can hear what the Corsa catback is supposed to sound like. Don't blame the catback man, the rasp is coming from the high flow downpipe.
