if you want power, look at a 2-1-2 system, If you like chrome, I have a dressed up set of V&H Power Duals on my '13 limited. The fit and finish is 2nd to none, they come with 220 degree heat shields and every nut, bolt and bracket required for installation. I also have an old set of V&H True Duals on my '03 and the chrome looks as good today as it did when i bought them. The quality of the system on my '03 is why I bought V&H for my '13
I picked up a ton of performance by ditching Rush TD and going with the Fullsac X pipe. Your ears will like you more for going with a proper headpipe also.
The Jackpot 2:1:2 is a far more efficient design than any true dual system regardless of manufacturer. There are other companies that make a similar pipe, however they're made out of mild steel rather than stainless, and they don't offer Jackpot's lifetime warranty.
If it were me (and it's not).........My opinion is to go with the Rush headpipe. I like the look better than the stock look of the Jackpots. They are ceramic lined and they have the scavenging feature (collector). As an aside, Rush is made here in Indiana and it puts my fellows Hoosiers to work
Thats the way I would go as well.....surprised to hear someone not endorsing the FuelMoto product,many die hard aficionados on this forum.
