new Drone free Dynomax Muffler?

But atleast with a pair of flows you will have arguebly the best sound for a 5.0.
More like an obnoxiously loud sound, with a never ending drone at 2000rpms.

Different strokes for different folks.
Numbers cant be argued....a lot of people dont buy flows because of everyone else already having them. And there's a reason for that.

Very true. But the FlowMaster 2 chamber and Deltaflow are only marginally better than the stock mufflers for performance. I had 2 chambers on my Mustangs for years, and I just outgrew them. I got sick of the drone. If you have a big stroker motor like mine with FlowMasters, the noise is almost intolerable.

If you want to get a quieter sound, then you are going to want a straight through Muffler. Either a Magnaflow, or an Ultraflow is about as quiet as you're going to get. Other than that, I don't know. Putting catalytic converters on the car helps a lot.

Borla XL's are pretty quiet.
I've got Magnaflow's on my Cougar, and although they're not anywhere near as loud as the Flowmasters, I still get a noticable amount of drone at highway speeds.
Dynomax Turbo's are about the quietest I've heard before these new models came out.

Good point. There is such a large range of applications...its hard to label 1 muffler as "the best". A great sounding muffler on a <300rwhp setup...like a 2 chamber flowmaster...is going to be extremely loud once you add 100-200rwhp.
For the average combination....any aftermarket muffler will be fine and wont make a noticeable difference unless you are powered by a turbo. Otherwise...weather will make a bigger difference. 5hp is not enough for me to forgo "sound" and choose power. An in most applications...its not a 5hp or 5ft lbs tq difference. The ever so popular muffler shoot out shows this...

Turbo applications....a switch from flowmaster to dynomax results in 30-40hp.
( will add high HP non turbo set ups will see a larger difference than what this chart shows...but i dont have any data for that.)Bassani will be my next muffler purchase.
Damn, 17 dyno runs to test mufflers? Surprised by the 10th run, that car wasn't making 50 less HP because the motor was worn out. LOL. j/k I think my 96 Cobra had 10-12 passes before the tune was perfect.
I agree with Nate...Flowmasters have got to be the best sound on a 5.0L. Drone...yes...but sound...you just can't beat it.
