I have them on my 85, along with high flow cat and stock front & rear Y pipes...only loud when I want it to be, and ZERO drone...not to mention plenty quiet enough on the highway at cruise rpm's.

Keep in mind video was taken between two house, so it's a bit louder than in person...
I took mine off in mid November and replaced them with the Mid America replacements...stock type mufflers have been sold, and eliminators are back on.

I ran muffler eliminators for about 3 years without cats. The resonance was terrible at 1700rpm. My wife wouldn't ride in the car anymore! I went with 3" duals with flowmaster 40's. The resonance is alot less but it still will rattle your brain slightly at 1700-1800 rpm cruising. But god I love that Flowmaster sound!

Sounds exactly like mine.
I have the same exact setup as you, but with an aftermarket rear y with the crossover tube (pointless).Here's a sound clip from inside the car at the strip:

Resonance is not a problem, at least with the cat in there. I cruise between 1700 and 2100 rpm on the highway.

I think they sound pretty sweet on my LT1 with an X-pipe and replacement cats.
Only problem is,I think the car lost topend hp/tq and lowend power aswell. Mojo showed how his car lost 1-2mph in the 1/4 mile dropping the mufflers and adding straight pipes. I think im in that same boat. Im gonna buy Borla XR-1 mufflers next!

I have Em with no cats and with LT headers, just lov em, its sure waaay to loud but i still drive it, b/c i love it and mine is a DD too and 80 miles roundtrip to work and i work 7 days a week.
There's some resonance but who cares hell iam driving a vette not a camry, who cares about comfort and what all i need is sound and power thats it.

edit: I'm new to the c4 - what are the piping diameters (in inches) of the header collectors, the cats, and the mufflers on a stock L98? what are the diameters of these aftermarket setups?

My '88 Anniversary has the Muffler Eliminators.
My car doesn't sound nearly as loud as rel3rd - kinda wish it did.
While it still has a nice rumble to it, most people don't really notice it much - they always seem shocked when I tell them the car has no mufflers! It does sound MUCH better than the stock exhaust, that's for sure.
I have never had an issue with drone or resonance.
Keep in mind, mine is running with the stock pre-cats, and stock cat, so I'm sure that is keeping the noise down.

there is no RAW sound about them. just an abnormal amount of drone and a very muffled burble

I have them on my '85. They're VERY loud. I was going to swap them out after 3 years of having them, but since I'm selling car, they're not an issue anymore.

I've seen people with B&B tri-flow system which in my opinion sounds incredible but very loud. If you search those threads a few guys have a trick where they plug the outer muffler outlets which significantly reduces resonance and has no negative effect on hp. Essentially you can have a killer system for those nights you feel liek screaming your beast down the road or put the 3" plugs in and have a nice cruise...just a thought.

Very strange that your car would lose BOTH low and upper power. Usually, it's one or the other, not both. I know I've done things to cars past and present, that people swore wouldn't make any difference, but I tried it anyway, and was happy that I did. Perfect example was bumping up my base ignition timing. The consensus was that it would make zero difference, but mine felt like I added 25hp...
NOTHING is written in stone.
