I had a 2010 Mustang GT, but the 5.0 itch had to be scratched, I found a great deal 3000 miles away, and the dealer agreed to give me what I paid for my 2010 , 2 years ago (NADA book trade in value). So I could not pass it up. I had Flowmaster American Thunder axle backs on the 2010, they were much better then the stock mufflers, but I wanted something louder for my 2012. I do alot of highway driving, and I hate drone. The American Thunder Axle Backs had no drone. I considered the Flowmaster Outlaws, and they sounded great (online videos), but everything that I have read said that they have a crapload of drone around 2K RPMS. My question is, are the GT500s axle backs louder and more intense then the American Thunders? If so, by how much? Do the GT500s cause any drone? How are they compared to the Outlaws? Any help would be appreciated.

 

no drone from flowmaster.
thats interesting.
i think the GT500 AB have less drone but are not as loud.
you should look into KR mufflers.

 

Roush Extremes = loud, but no drone.

 

Going by this guy, who has a roush catback, says its got bad drone at 2000rpm

He went with magnaflow

 

I cant speak to the Flowmaster's other products, but the American Thunders had no drone, and still had *****. (Although, I still wanted it to be louder).

 

I Googled Rousch Extremes, and could not find them. I found Corsa Extremes, but not Rousch. Which Rousch model are you referring to?

 

Roush extreme catback with midmufflers
Those are great too
I think every exhaust has drone, even stock
But some more than others

 

Yeah, my car has 550 miles on it, I still want to keep as much of the warranty as I can. Does Rousch make those in just the axle backs?
