Alright guys I found what I am going for. I am getting the Megan Racing M-Spec II turbo muffler. It has a 4 inch tip and a 2.9 inlet.... not that far at all from 3" so it shouldn't be bad at all. I will post up pics as soon as I am done with the whole thing. Hopefully I will get the muffler by Friday that way I can do the job this saturday, if not, next week.
