Well, as a few of you may have seen I now have my Magnaflows installed. So for the rest of you I figured i'd share.
I went with the universal muffler 14814...
It took some customizing in order to get them to fit, but at the moment I am happy with them. The resonator was cut off and I went with 2.5" pipe from the cat back. The local shop also painted all of the piping with a high temp black paint...it looks clean and a bit stealthy. Here are a few pics of the install and a link to videos.
