I run a fatcat on mine with a "quiet" baffle as well. I have a black one and the finish is second to none. Getting to the top rear bolt is a bit tricky due to the shape and bend on the pipe but aside from that this system rocks. My TH bracket cracked in 3 weeks, I rewelded it and it cracked in another spot. Plus their black finish turned brown in a few days.
The fatcat has been on about 6 months without issue. No need for a lowcat on my bike as I have an FXDXT with stock 13.5" shocks. D&D is hard to beat for fit and finish. The sound is that of a muscle car in my opinion. With the quiet baffle it is not too loud at idle but barks when you get on it. It has a much deeper ruble than with the standard baffle.

I don't know if I would say "unmatched performance" as I ran the Thunderheader prior to the fatcat and it seemed to kick out a little bit more low end than the fatcat until I rejetted my carb. However you toss it, it is a great pipe, but it seems most Dyna guys go with the Thunderheader due to what they see on TV.
After my experience with Thunderheader I will never run another one of their products. All of the quality 2 into 1 pipes will provide relatively similar performance within a certain range. I wanted to clarify this for those who may interested as some of these answers can be a bit misleading.
Obviously a lot of the performance has to do with other mods on your bike (a/c, jetting or tuner, etc) How your bike is tuned will affect the power and smoothness drastically. My personal experience on an EFI bike is that a canned map will help, but a Dyno tune will really dial it in so it rides great. On my carbed bike (yes I have both) the jetting and afr are of paramount importance as well. I much prefer a carb as it is so much easier to dial in albeit less expensive too unless you have your own Dyno.
The bottom line is that if you are looking for your bike to run as good as it possibly can don't skimp on the tune or tuner and you will understand what I am talking about.
