I ran a dry for about a year and it was great, no issues but I was getting close to the end of the dry units life, and I've been waiting for months for S&B to restock. I just swapped over to an oiled unit, pretty happy with it so far. I was initially team dry, because i didn't want to deal with the cleanup+prep, but it's not that bad. Red also looks cooler.
Difference in sounds between Oil/Dry is negligible. both are a substantial bump from stock, but you are looking at 120% vs 119%, not really a enough to move the needle between which you choose.
If you end up going with the oil version, i recommend either getting a second filter or a dry filter, it takes about 24 hours to finish the clean+re-oil.
