Most Aggressive sounding muffler for 5.4?

I'd be curious to hear what the Dynomax Ultra Flows sounded like on the 5.4 I had a set on my 5.0 Mustang and they were the best sounding mufflers I had ever heard on that car. The Mustang I bought last year has MACs on it and I absolutely hate them. I'll be switching over to the Ultra Flows this year and I'm thinking of putting them on my 250 also. Nice deep sound without the drone or the raspy-popcorn crap.

This is my gibson dual extreme exhaust on my 03 5.4 I really love how it sounds, its gotten a much nicer tone since i installed it last july. No drone on the highway and not obnoxiously loud. Ive been told it sounds like a V10.. but im not sure. I heard the guy doing my tints start it when i was about 30 feet away the other day and couldnt believe how nice it sounded. really had a sweet growl at start up and driving that i could never hear in the cab

I've used glass packs quite a few times. They get louder the longer you run them.
Glass packs tend to get louder the longer you run them, which is a good thing if you want a louder sound.
I have listed here a muffler shootout test done by CAR CRAFT:

DYNO TEST
All mufflers were dyno-tested on a 355-cube SBC with 10.0:1 compression, Air Flow Research 190 aluminum heads, a CompCams 292 hyd. a Victor Jr. intake, a Holley 750-cfm double-pumper, and 1 5/8 Headman headers.
While there are mufflers that will out flow a glass pack design, it also depends on the design. Does the glasspack use "louvers or perforations" - Louvers reduce the flow by as much as 50% but Allied resonators (that sell for $30-$40 each and available at any muffler shop) in independent test flowed 90%+ of a "race spec muffler". Others using other brands consistently showed similar results.
The CATS absorb about 60-70% of the sound........IMHO, I would go to a local muffler shop & have them drop the muffler...listen to it, it may be to your liking....if it needs the tone changed, then have them hold up different mufflers until you find "your sound".
I am running 2- 3" diameter, 24" long Allied resonators on mine.....they are very deep toned, nice rumble on accel/decel and little to no drone (depends if the weather is raining, then there is some, but very small- not enough to be an irritant). I (and my family) have used these on just about everything since the 60's and have never had one "fail" or loose it's sound, etc.
