I always use bullets (glass packs) in the tail pipes to control the drone. Never used any brand name bullet, just the cheapest I can find. And I have never paid any attention as to direction.
They do a good job of controlling the drone.

I've used em (not cherry bombs but glasspacks in general) & they do work. Pick glasspacks that do not neck down at the end nipples & have the open ends of the louvers forward to catch some of the sound waves.

I have 440 with 2.5" exhaust and 2 chamber flowmasters. sounded fine with headers but when I put HP manifolds on it it droned and wanted to remove my fillings. I used summit brand bullet mufflers just before my exhaust tips to stop the drone. worked perfectly.

I had the exact same problem with the same exhaust system on my 69 GTX. I installed two Summit JEX-A4512B glass packs just ahead of the tips. There are two ways to put them in, I selected the low back-pressure mode, no drone at all now.
not to steal the thread, but...did the glasspacks do anything to quiet the exhaust?

The Cherry Bombs I had on my GM p/u were so loud, I took them off after one day and cut them apart, just because. Mine were not louvered, but punched, so I would suspect they were uni-directional.
As a sole sound dampner, I would expect that. As a resonator used in conjuction with a regular muffler, much less so.
Snce you already have mufflers, I'd instll them in the higher flow direction. They are providing additional dampening, not the only dampening.
