Flowmaster axle back mufflers for 11-13 GT's

[timfoster405]

Can someone quickly tell me what series Flowmaster mufflers are the quietest?

I have an opportunity to get a set of flowmaster american thunder axle backs very cheap.

Will they drone w/ factory cats?

thanks,

(P.S. I have search some... but could not find my direct answer... and I did view Americanmuscle's youtube video, but that was for the entire cat-back set-up)

i think hushpowers are the quietest with outlaws being the loudest. outlaws droned like crazy

Hopefully flowmaster has corrected its issue with the american thunder mufflers. They had a qc issue and the baffle welds were breaking causing a rattle.

i have hushpowers on my car, i dont notice any real drone, and they sound deep, and its really not too loud

good to hear...I wonder if that is why this dude is selling them

the American Thunders do drone quite a bit, doesnt bother me but most dont like drone. I had Hushpowers and they were too quiet for my taste

i am contemplating putting my 3in deletes back on though

Now I see that '13's have a different part number...is the valence different?
