I ran this one on my previous ride, which was an '09 Street Glide...... Still contemplating putting the same one on my Ultra......

 

Took a chance on the PM Merc and I think it looks pretty good. Really like the K&N filter too.

 

thanks for the clarification.

 

My research came up with it breathes better that a stage 1, so if you DO have cams and the motor requires more air, it's ready to go. I've got stock cams but V&H Dressers and Rinehart 4"ers and my bike required a tuner. It ran lean as hell. Fuel Moto dialed me in with a PCIII, it's been amazing ever since.

 

i called AN to ask them since the only difference between their stage 1 and stage 2 was a 20% increase in size, however both descriptions were the same - may increase hp by up to 21%. i was told the stage 1 version is for mostly stock setups, stage 2 doesn't add any real benefit unless you have ported and polished and therefore need more air.
