headpipe
how much is to be gained by just adding a headpipe?? I see everyone is doing it but i'm curious to how much you gain? I have a 2011 road glide custom with pc-v, arlen ness big sucker, and screaming eagle slip ons! I realize your getting rid of the cat. but curious to what else you gain? As always, thanks in advance!

most do it to decrease the heat and add a little volume to the pipes. as far as performance goes some say it turns their bike into a 3rd gear wheelie monster and some say it makes no difference..... fullsac did a test a while back that showed the cat didn't hurt performance untill you had an build capable of 100 plus hp.

After debating for awhile I switched to the FM 2-1-2 head pipe. I did it mostly to increase sound, cats just muffled the nice rumble, now sounds great!! While the head pipe heat did not bother me much, I did realize a big difference there as well to the better. As far as power, was not expecting much of anything. I think I feel a difference, maybe because I have it paired to FM 4" Dyno Tuned exhaust and New PowerVision map from Jamie. Overall the Much improved exhaust note and bark is awesome and made the price I paid worth it!!!

I went with Rush Racing Cermi-Coated true dual head pipes... I wanted the dual sound, and I love the looks (The Rush head pipes have about a finger's width spacing between the front and rear pipes on the right side before the rear pipe goes under the frame... I like this look better than the others out there that lay right on one another) and the double ceramic coating (inside and out) Looks great and further reduces heat! I love 'em

In order to run a "true dual" you have to have a different head pipe setup to start with. The stock head pipe is a 2-1-2. True duals keep the pipes completely separate from the jug to the muffler.
HP/TQ numbers are argued back and forth, but unless you are really building a serious motor, I don't the the gains/loss will really be noticeable.
Performance wise, a good 2-1 is supposed to be the best setup
