I got luck and added an air cleaner around my 16k mark (stage 2 big sucker) that I got dirt cheap. Then around my 25k mark I added the Xieds and then the Rine Harts around 27k that I also got dirt cheap. Just did my 30k service (32k on the bike), I pulled my plugs and they looked perfect. Bike runs great. I do want to get a tuner soon, maybe while I am in Milwaukee next month.

 

On my 07 FXD I have Demon Cycle Y pipes (LAF) and a stage 2 big sucker. Runs great. Sounds better. I haven't noticed a terrible loss in power anywhere but low speed torque. The decal pop is incredible and I shoot blue flames to the ground. I was going to buy a tuner, but after reading this I don't think I will.
