If you have straight pipes i imagine you like it very loud-so baffles will make it quieter and you don't want that I think. You just need some type of fuel management device like PCV, pcIII, sert,tts master tune, vance &hines fuel pak.... There are more...

Doesn't FI require a decent amount of backpressure?

Backpressure = Power

Straight Pipe = Noise

Power = Win

Noise = Fail

It will run like crap with open 2" pipes. Save your money on that BCT crap and just get you a set of 12 buck shorty baffles. If you need to do any "tuning", make a pair of lollipop baffles and put them in either before or a after the shorty baffles.

i run 1 3/4 inch drags on my 06 superglide. mine felt like a dog with no pipe mods

i had to drill holes in the bottom of the pipes and stick screws up in them. after that it made a big diff. in torq. I love the sound and looks be sure to get a tuner though.

No. When you change air cleaners later, yes.
