I heard my Indy's 2015 Road Glide with Fatcat with louvered baffle that he just installed, and I believe it was quieter then my long shots I had on..but I personally like a loud pipe.
I've seen the results first hand on my FXDWG. Went from 99/105 to 114/117 with just the swap from V&H Big Radius to the D&D and a correction in the tune.
That's not a good comparison seeing that those V&H were probably one of the worst out there for performance but they were loud.... and I know cause I had a set....

IMO you can't have a better comparison between two systems. The V&H's 2 into 2 Big Radius are one of the exhausts that everybody on the planet and their dog thinks are the schizz-nitt on a Harley and then there are the 2 into 1 systems in which many riders say that their main reason they don't care for them is the overall look of the system. It's all about a matter of esthetics, but the differences in hp & tq I posted about were done by the same tuner on the same dyno using the SERT and under almost the same exact atmospheric conditions. And yes both systems are loud. Very loud!
