If possible, once you get that pipe on, get a video with sound of it and post it.
I'm gonna get a video of stock pipe, and then my Q4 once I get that on. (this weekend)
Should be interesting to compare noise levels and tone.
The programmer debate is almost like oil.
Look at the prices, look at the features, consider the application you desire and then pull the trigger. You can't go wrong with any of them really.
I'm not sure there's any real advantage or disadvantage between the FmF and the Attitude. They are basically the same unit and do basically the same thing at slightly different prices.
