I too was going through exhaust selection overload. I knew I wanted to do something as the stock exhaust was just too quiet, and in my opinion did not sound like a Harley. But what I did not want was obnoxiously loud. Looks were the second most important factor, and performance third.
What I ended up going with, for lack of finding anyone that could tell me just how loud the different pipes were compared to each other and stock, was the Screamin Eagle II Pro slip-ons. I had them installed at the dealer along with the Screamin Eagle Race Tuner. The slip-ons sound great and I'm very happy with the amount of loud they have. Now my bike sounds like a Harley.
What I do not know is if the dealer actually dyno tuned my bike or just loaded a default map for the slip-ons and ran a dyno run to show me the values. I only received one dyno print out so have no way of knowing what the hp and tq were to start with. I ended up with 93 hp and 96 tq and a straight line for the air/fuel mixture, which the dealer thought was great.
Do these numbers seem reasonable for slip-ons and a race tuner? What are the stock numbers without any modifications on a 2006 SE Fat Boy? Can I do better if I find someone else to dyno tune my bike?
I would include the dyno printout, but do not have a scanner. Maybe I can just take a picture of it with the misses digital camera. I will try that tonight.
Thanks,
Roger
