DynoMax Super Turbo vs. 2 Chamber Flowmasters

Unit:

That's why I stayed away from Dynomax, I heard them on a car and it sounded like a small block chevy with glass packs. I am not trying to be a wise a$$, but that is seriously why I stayed away from Dynomax.

Aren't Dynomax super turbo's straight through with fiberglass packing. I haven't heard of the ultra flos, do they sound better than the other Dynomax mufflers? I would consider these if they sound better than the super turbo's and have less drone that the flowmasters.

Thanks,

Jason
