You should see gains throughout the whole power band, but not too sure how much yet. We are working on the 2012 system now.

I bought this same system for my 2011 Unl. rubi; the muffler that comes with it rested directly against the frame at the front of the muffler. I could see no way to adjust it down because its close behind the stock exhaust that stays where it is. I don't mean it was close to the frame; it was firmly pushing against the frame; a solid connection.
The other problem with this kit is the muffler that comes with it is very loud and drones like crazy.
The other problem with this kit is it exits straight out the back. I know it's supposed to be "high clearance" but a slight down turn would be much better to help get the exhaust gasses away from the Jeep.
I paid a muffler shop to put a quieter muffler on and they welded it in place so it doesn't hit anything like the muffler that comes with the kit.
I also tried to contact Dynomax on their web site and never got a reply.
Save yourself some money and just have a good local muffler shop fabricate you a system or buy another system; not reccomended.

Great Write Up!!
 
This was a very good write-up! The instructions included didn't help to much but it was an easy install thanks to this write up. The only problem was the tip that I got does not fit. It is way to big for the tailpipe. I email Dynomax tech support to send me a new one lets see how long it takes them to get back to me.

Often times with that tip you have to really tighten it down, a lot. FYI!
