Make sure to get the Screaming Eagle flat gaskets...which contrary to the V&H website, were not included. (A second trip to the dealership if you didn't figure that out on your first trip.) Looks & sounds great!
The shipment was shy a couple of clamps for the heat shields. The folks at Vance and Hines make a great product but not so good at simple counting. No problem....we made it work. I think I will still use the ear plugs for long highway rides but that is a small price to pay for the gains in performance and the unique sound of this pipe. I'm truly impressed!
The biggest problem I had was a Harley problem not a V&H problem - removing the stand-off bracket that held the OEM pipes to the transmission. The install instructions said to remove the oil dipstick cover and the transmission cover. I was unable to remove the transmission cover no matter how hard I smacked it with a rubber mallet after removing the bolts. The best I could do was remove the bolt from one side of the bracket and loosen the other. The clutch cable prevented removing the 2nd bold.
Once loosened the bracket would pivot then I had to cut the bracket as best I could then re-tightened the bolt with stub that was left. The new pipes would hide the stub so I am OK with that.
The install kit comes with a mounting bracket for the 5-speed and the 6-speed transmissions. The 5-speed bracket worked perfectly.
The next installation problem I encountered was a V&H problem. The right foot board needs to be removed. The V&H kit provides 2 extra washers for both mounts of the foot board to act as spacers to move the foot board outboard to accommodate the new pipes. On the 2006 FLHRCI two washers are not enough. I had to use three to get clearance. This means you should be prepared to obtain an additional suitable washer to get clearance.
Follow the instructions to the letter and in the exact order when installing the heat shields. I thought I knew better then leanrned why the instructions are the way they are. I had to remove stuff then reinstall the heat shields per the instructions. Don't think it's bull. Just RTFM (read the f****** manual) and you will save youself a ton of hassle.
The lower heat shield fit perfectly. The upper pipe heatshield does not align as nice as I would like. No amount of flexing the shield would get the perfect fit like the bottom shield. The look is OK but I would have preferred the seams of the upper and lower pipe to be identical.
Now the good stuff. The pipes have an awesome sound. Exactly what I was looking for. Low baritone rumble that gets attention. The bark on acceleration when you hammer the throttle is very exhilerating. I have the V&H high flow V02 Naked and the air intake and the fuel pack. The increase in power is obvious in the seat of the pants from the first release of the clutch. I will be using earplugs on long rides.
These pipes, intake, and fuel pack are exacely what I wanted for increases in power and an awesome sound. I am very happy with the purchase and the performance. Just had a few installation and fitment hassles that I might have been better off without.
