Get a Fast Intentions exhaust with milspec cats if you want cats. Another option is Motordyne, they have some cat options to integrate in their exhausts
An 18" resonated fast intentions exhaust with cats built in won't drone much. The Ark DTS is a quieter exhaust, but I'm not sure if it's any better than fast intentions with drone.
I have an AAM exhaust on my car now that I'm selling that doesn't drone. It's comparable to the Fast intentions exhaust power wise and they based it off the Nismo exhaust. If you're interested, just PM me.
