Loaf,
Not sure about the H pipe scenario, I know HD says it adds considerable improvement to the twins, but not sure on ours. From what I've read the H is really only designed to eliminate the imbalance in systems with unequal length pies/mufflers. I guess that would equate to better flow???
I ordered a new set of headers from Marv at the rally, and they are the tri-y style that supposedly give you the boost in the low to mid range
.....about 30+ hp on Marvs' dyno tests. Not sure what they sound like either........but they bolt to the stock holes, utilize the stock header covers and have the same appearance as our stock system.
