Are you running a catless setup like CSG Mike?

So If i were to have high flow cats with a Perrin Catback would the noise level be a little more quiet? I don't think I'd mind the noise to be honest but I don't want to get any tickets or noise complaints from my neighbors, even though he's got an annoyingly loud mustang lol
