Anyone running Dynomax Ultra Flo Muffler?

[overlord1]

I've got a bone stock '06 Silverado 5.3L and was toying with the idea of cutting out the factory muffler and welding in a Dynomax Ultra Flow SS muffler and keeping the rest stock. Anyone running this muffler? How do you like the sound? I definitely want louder than stock, but not obnoxious. I'm wondering if this muffler drones/resonates badly cause if it does I'll definitely pass on it. I also thought about the Dynomax Super Turbo muffler but it sounds like it would be too quiet, barely louder than stock. I appreciate any opinions/suggestions. Thanks.
