I'm going to go with a UPR; I think the extra $40 are worth it, and less clutter. And a much larger can too (8oz). Didn't like the crappy fit of the FP, especially on a Bullitt, since it has the intake inlet deeper than regular GTs, and it stresses the lines a lot, and also leaves the unit at an angle. At any rate, you're supposed to install a nut BELOW the bracket, to clear the head. Did you do that, MustangMatty? Maybe you didn't get that 'spacer' nut. Good luck.
