I know this has been covered many times before, but would like a recomendation for a better exhaust system for low end performance. I have read alot of the other posts on this issue. I have a 98 fatboy with a Dave Mackie dm500 cam (bolt in) and Vance and Hines big shot stagger exhaust (no baffles). Jetted CV carb. The thing suffers from lack luster performance until the cam kicks in at about 3800 rpm. Looking for low end torque. I could order baffles for the Vance system but would rather look at another system. Thinking about a Vance Pro pipe (chrome). Thoughts.
