Flowmaster or Magnaflow for my tahoe.

I have been thinking of putting a exhaust system in my 1999 4X4 Chevy Tahoe does anyone have any opinions on these mufflers Flowmaster and Magnaflow.

I have a 99 tahoe with 3" flowmaster duals. The sound is incredible and you can really feel the performance change. Plus these little 4 bangers quiet down when you come rollin by!!
