stick with a 2:2 system, unless you want to lose power. V twins perform better with dual systems.
2:1 systems usually provide, little if any gain. They are great for sound though if thats what your after. I had a mivv 2:1 on my Aprilia, sounded great but the bikes performance across the powerband was garbage. Soon after i got rid of it for an Akrapovic system and it was like having a completely different bike.
If its looks and sound your after (even though i think most duals sound a lot better), then by all means do it but realize your bikes performance is going to suffer.
