Went on fairly easily. Sounds awesome.
The install wasn't too hard. The flange holes didn't line up well so I had to modify the flange a bit to get it to work, but in the end it looks and sounds great. In the end, my only concern is that there is a rattle that I can't seem to locate easily. It didn't exists before so I know it has something to do with the new catalytic and/or muffler. I think it might be the shroud on the muffler. I need to take a longer look at it. I'll update this post when I have an answer.
