I have the same magnaflow and have nothing but good things to say, my brother got his from ebay but I wanted a valid warranty(I have had problems with ebay sellers before) so I got it here. magnaflow 16454, or you can try one of the vendors here on the forum selling magnaflow, they are allways having sales/specials on the forums. It is nicely built and sounds great I think.

 

here's a clip of my magnaflow with two glasspacks. there's a small flange leak because i unscrewed it to put in a new flange.
