The RPI acually has the merge after the normal spot. I think gintani is the only one that moves it forward. The downside of moving the X section around is it can effect the sound, usually for the worse we found according to customer feedback. Ive never seen any back to back dynos that have shown more power by moving the cross over forward, even in our own development
