Ok guys. Here's one for you guys. I have an 03 flstc injected with Bub 7 true duals. I'm not getting as much bang for my buck in regards to hp/tq. I know 2to1 is the best for performance but that is not an option atm. I saw an 03 softail springer with stock duals and got to thinking. Do the stock duals with the crossover y-pipe make better hp/tq than the true duals? My thought was perhaps finding a set of used springer headers and running them with my Bub's 3.5 mufflers. Anyone have any input?
