No cats here, and yes it is louder. A lot louder! You will be cop paranoid for certain. A resonator or large muffler after the turbo would take care of the increased noise without affecting flow.
I did notice a spool difference, it got a little better and felt stronger as well. Never had dyno before or after results though.

yep. Put maggie bullets in front of the turbo. As long as the muffler doesn't drop the flow, it won't hurt your performance, and may actually help with spool times
My beast is back to stealth mode baby. Sounds like a catback only
BTW, if you leave the cats on you don't need a muffler. An alternate might be high flo cats, but I'd worried about chunking them and sending chunks back trough the turbine. I have cats for inspections / test pipes for the rest of the time for mine.
