No Catalytic Converters

Smart move on the refund. Most tuners are happy to tune your cat-less car with a disclaimer that the tune is meant for off-road use only. Sounds like someone doesn't want your money lol

Am I ruining my car by not having them?
Absolutely not! Anyone that says differently is trying to sell you something.
Does anyone know a good tuner on the central East Coast that would tune a car without cats?
Hills Garage and R/T Tuning are both very reputable shops that have significant 370Z tuning experience and are not terribly far from VA
If I do get cats, which ones should I get to make the most power?
HFCs will give you more power than OEM cats. There are a number of vendors to choose from. I recommend Fast Intentions.

To follow up with what Jar has stated.

The tuners he recommends are very good. If you're technology competant, you could also reach out to Sebastian from Specialty Z. He does remote tunes. You essentially plug your laptop into the OBD port and collect a data log for him. He tweaks the log and sends it back to you with instructions on what he wants to see. Rinse and repeat a few times. Wala, you have a tuned car.

Jars recommendations on fast intentions pipes are highly respected. Very solid handcrafted work from a very reputable place. Only downdraw is they usually have a decent wait time on fabrication.

Personally, i'd go with HFC's over TP's, but that's just due to the loudness and smell they can give off. Totally your call though. Neither will hurt your car in any way. You may just feel the car is acting sluggish until a tune is done. The ECU's for our cars is very robust at keeping up with bolt-on mods.
