Thanks, for the comments. I bought the bike and it was nice but I hated the sound. I took it in at 1400 mile and had the Stage III done. It ran good but I wasn't satisfied with the sound. Due to the voiding warranty issue, I was reluctant to modify the exhaust. I didn't ride it much the first year. Then I decided to go ahead and get her up graded to my liking. I added the D&D 2-1 exhaust, with ghost pipe,in black. I already had a Power Vision Tuner so I bought the dual tune license for the bike so I could use it on the bike. I also bought the DynoJet Target Tune and added it. Got a tune with my mods from FuelMoto, auto tuned it several times and man she's a beast. Runs great and sounds great too...
