Manaflow 07 - Dual in/single out or true duals?

Hi I just had a magnaflow put in yesterday. most people are saying to put in # 12256. that has a 2.5" pipe they make a 12597 that uses a 3" pipe. I had them cut it off just past the cat and replace the 2.625" pipe with 3" put in this muffler and used the stock tail pipe being that it already is 3". All this for $150 out the door. It sounds wicked. Was a little afraid it was to loud. Took my wife to the store in it figured she was going to frown on it. She asked when can we do her Suburban. For the money I made my own cat back single that sounds better than any car or truck I have ever owned. Hope this helps
