Whats the best combinations to get maximum cubic inches and power out of this 103? I already have the screaming eagle heavy breather on it, I bought the bike used last year had 6600 miles on it, it now has just under 11,000 miles on it. I'm pretty sure it has the factory pipes less the baffles, because it has a louder tone then other stock Breakouts I've heard. I plan on using the vance and hines long radius street sweepers on it with the heavy breather. So what's the best way to get max cubes, hp, and torque?
