If you want just a muffler I’d recommend the 22” muffler PN# 12588. It’s the same one used in the Magnaflow Catback and it has zero drone. It uses a larger case size (5x11) vs (5x8)... That’s my 2 cents worth.
What Mango said!!!!
I've been doing the same research and from what I've dug up all over the place (including the local muffler shop) if you run a 5x8 muffler (regardless of make) there seems to be a whack of issues with drone. I'm going with the 12588 when I can scrape up the extra coin.
