Interesting question, looking for opinions.
Go to nightrider.com and see data fromFall 2006 Enthusiest showing that baggers make much better torque numbers than Dynas. Reason is the crossover pipe & large muffler volume / backpressure. In principal that does make sense to me.
So, they say HD claims an 07 Bagger gets 71 HP / 90 Tq. at the rear wheel stock, and with Stage1 (#29773-02C) & SE Mufflers (#64985-07) they see 79 HP / 96 Tq. at the rear wheel. Of course, all falls off past 4,000 RPM's.
Overall this makes sense in theory, but if correct then MOCO has done a nice job and the Stage1 / SE Mufflers does produce results.Most people claim the Stage1 / Download is a waste, but I kinda think it deserves a closer look.
I have an 07 FLHRS on order and I just may give this a try.
