Well, I swapped out my muffler again today.....I believe this makes my 11th muffler to date. If I recall correctly, I've had 14" Magnaflow, Borla Pro XS, Spintech 9000XL, Black Widow Venom 250, Solo Performance Mach 44, Flowmaster 50HD, Spintech 3000XL, 18" Hearthrob, Spintech 8000, 24" Magnaflow....and now a Dynomax 6" round Ultra-Flo. If interested, you can search my older threads for a rough breakdown of some of these.
I've been after a deep sounding exhaust with a descent amount of outside noise, but low interior sound with no drone. As you know, that's a hard combination to find. Some of the above failed miserably, while others were pretty good....but I just can't leave well enough alone.
So far I'm really digging the Dynomax Ultra-Flo. It's the 6" round model with 16" case (PN: 17223) 3" in and 3" out connected to a MF y-pipe. It sounds awesome. Deep tone and no drone. I've been driving around my normal routes and I haven't heard the least bit of drone (where I'd normally hear it with other mufflers). When I opened the box and saw how small the muffler is I thought it was going to be loud.....it isn't. Loudness wise I'd put it in the 14" Magnaflow territory.
Interior volume is lower than the MF 24" I've been running for the past few months. Exterior volume is definitely louder and deeper. It seems to be quieter at idle, but roars pretty good when accelerating. I'm not sure what will happen when I get more miles on it, but I'm really liking it so far. This isn't a muffler that gets talked about very much, but believe it ought to be on people's radar if your looking for a deep tone exhaust with very low interior noise, and healthy exterior volume.
I'd like to send a shout out to member abouttobeglue as I came across this Dynomax muffler reading some of his posts about the Gibson MWA race muffler.
