I followed the DIY in the forum here to remove the stock exhaust. With the right tools, it wasn't very difficult at all. The exhaust fits just fine. Noticed a little scrape on the bottom from me being silly and not putting it on something softer besides the concrete, but it's not like anyone will see it so it doesn't matter. The whole process took a little over 3 hours for me to complete, and I'm not very handy or good with this stuff
Here are some pics during the install process...
