Well, the amount of drone you can handle is subjective to be honest.
To me personally it's a 2/5 in terms of drone with 1/5 being little drone and 5/5 being headache inducing. It's there but not bad.
I have had that exact same setup (swapped for the Greddy Revolution RS because I like the old school single exit look) and let me tell you know it is much better than the Greddy Revolution RS and Borla Touring Axleback I had...and currently have.
Both of those exhausts gave me headaches on extremely long drives.
The Nameless Axleback with 5 inch mufflers pales in comparison to what those two deliver.
Although the Blitz Nur-Spec VS styleD was my favorite and to be honest I miss it dearly and wish I never sold it. It was a rare exhaust. Depending on your price budget, I recommend that catback for you.
I sadly do not have an interior sound clip but take my word for it that it's the least droniest of the exhausts I've had.
I would rate the Blitz exhaust drone level as a 1/5.
You may also want to look at the Perrin Catback. I haven't been in a BRZ/86 for that long in one but being the passenger in one, it's not that bad...and it's not that hard to find unlike the Blitz VS styleD.
EDIT: Just saw your price budget. I recommend saving up a little more. For 200 more you can get the CSG Spec Touring Exhaust which is very reasonable and I've also been in a car with that exhaust with Gruppe-S. 1/5 drone level from me.
There's also the Q300 which I have also had but, not with headers unfortunately. A fellow 86club member for the group I'm in says it's very reasonable though with UEL. Sadly, it's heavier than stock but not by much - and it won't matter much at all unless you're super ultra competitive racing.
