I just did the install yesterday as well! I just did it last night. I too took the console off though I was reluctant. Me and a buddy did the install and we talked about taking the console off and both blew it off thinking it would be too much work. We ended up having trouble getting the plastic piece unclipped that held the shift cables in so we decided to try to take the console out...
DEFINITELY TAKE THE WHOLE CONSOLE OUT! DO NOT BE LAZY! I saw somebody else try to say this on here as well and I ignored it! Taking the whole console out takes hardly ANY effort and results in more workspace and a much easier time remove the shift cables. There were two screws up front where the cig lighter was, two inside the center storage section and two in the back on each side behind plastic covers that the front seats covered up. And then disconnect the additional center power outlet and it comes right out. Soooo easy and totally worth it!
The install took us a total of a little over two hours. We used a rotary/dremel to do the necessary cutting and that was easy. Be careful when cutting the piece that is on the stock shifter stick - We covered the plastic parts with a towel and I'm glad we did because with all the sparks flying off the rotary cutoff caught the towel on fire. No big deal, but I'd rather burn the towel a little than melt the plastic piece that was still stuck around the shifter.
Shifter has a little added effort but the throws are definitely shorter and overall it feels much smoother. Feels like what you'd expect from the shifter on a sports car

I love it!
