If you don’t care about the warranty then you can use anything you want.
But if you do care about the warranty, then you will need to find some pipes (Yaffe’s web site says they won’t work) with O2 bungs andmufflers (to increase performance without any flat spots in the power band) (drag pipes, strait pipes or whatever else you want to call them kill performance) and wait for a couple of months for Harley to come out with Race tuner for the 2008 model year. Please have thebike tuned on a dyno also.
I know that people are not going to like this answer because there are aftermarket tuning kits for Harley’s. But other tuners will void the motor warranty andyou should know this before you do something to void it.
