I have a 2007 FXDSE. I also posted this in the 2007 FXDSE section
Well, I finally took the plunge and put on new pipes.
i put a set of Vance & Hines Bigshots with quiet baffles. Also installed a Power Commander 3. The ace mechanic at Yamaha (worked at Harley for 10 years) put her on the Dyno this morning and did a custom map. So here are the numbers of 3 separate runs: Air temp was 68 degrees F.
1. 96.86 HP______ 113.12 ft/lb Torque
2. 94.04 HP______ 108.03 ft/lb Torque
3. 94.59 HP______ 108.79 ft/lb Torque
He figures that the first run was at optimum motor temp. He tries to tune it with a infared meter so the cylindar is 200-208 degrees. I took the day off to watch. It was pretty amazing seeing all the setings and different things he had to do. I had no idea it was so complicated. It was on the Dyno running for 2.5 hours. Man the noise!!! I had ear protectors on and it was still loud. He took it up to 6900 rpm a few times. I had a full tank and when he was done I had 1/4 tank of gas. There is a noticeable increase in thrust and smoothness. I took Connie for a ride and she noticed a big difference. I might even go as far as to say that it may even be fast. I could have gotten more with a 2 into 1 pipe, but they are kind of ugly. These pipes are 2 into 2 with a power chamber. I was ver suprized at the numbers. The tuner was also suprized. Thiswas his first CVO 110 cu/in motor that he tuned. The max torque is at 3500 - 4500 rpm. The Max HP is at about 5K. Very smooth map. The torque starts dropping at 4500
The drawback is they are kind of loud even with the quiet baffles. When Connie and I left today I took it real easy leaving and I still set off a truck car alarm. I saved the stock pipes so when the Cal EPA starts testing bikes I can switch them back. All I have to do is disconnect the PC111 and the original "Lean" settings are stil in the ECM. I never had a loud bike, but I must admit it sounds pretty good. I noticed a big difference in engine heat just cruising down the hiway. I think I even got the front wheel a little off the ground when I was hammering the throttle.
