i realize that sound clips are worth more than any words but I can not supply sound at this time so...My father and I just exhausted our trucks this week, Both 6.0l, true dual, di/do mufflers. his is a mag 14568, 2 1/2", turned down tips at the bumper. Quite an awful drone between 1700 and 2500, too loud inside the truck, in our opinion. mine is a dynomax ultra flo x, 2 1/2" exiting behind the wheels. Louder than the mag outside deep tone, much quietr inside at cruise, no drone, sounds awesome. highly recomend that muffler for a deep, rich sound. Art

 

i have the dynomaxes and i love them . always will reccommend them.mine dont have drone at all and sound awesom,nice and deep.theyre the straight throughs that look and are built the same as a flow out of the thick alum.

 

I had a dynomax bullet with a turn down. Hated it, way too quiet inside and out. I kinda liked the flowmaster tone, but loved the magnaflows on my old V6, but I think I'd still go with the magna any day. We'll see how I like my flow after my headers are on

 

magna is too loud for my taste i run true dual dynomax straight. It's only loud above 2400 rpms but nice and quite while cruising. I like to hear my music or talk with out raising my voice LOL.
