Hi, I want to upgrade my head pipe. Looking at V&H Power Duals and Dresser Duals. I like the look of the dresser duals but like the possibility of more HP from the Power Duals.
Has anyone else considered these 2?
Any recommendations or regrets?
P.S. I think the power duals are only avail. for 09's

 

bump....
No recommendations?

 

here is what the harley tech at vance and hines told me about the power duals vs. dresser duals

1- the hp increase with dresser duals will not be very much-not even 1hp so might as well stay with the stock heap pipe for the money
2-the best performance will be from the power duals with a slipon muffler
3-the slip on will give + 2hp and power duals another 3-4hp for a total of 5-7hp

i just bought the power duals and a set of slipons. if you look at the stock harley cross "under" pipe you will notice that is a very small O.D. pipe and almost looks crimped. that can not be good for exhaust flow.
thanks

 

You think his opinion might be slightly biased as he is a tech for V&H?

 

well he may be biased as far as him saying buy the power duals instead of Cobra or Bubs but he said himself all the dyno runs with the dresser duals head pipe didnt improve the hp that much over stock head pipe . if he was biased he would have said to buy the dresser dual head pipe no matter what. him and i agree that if you are going to spend 300 for the dresser dual head pipe spend the extra 100 or so dollars and get the power duals and get some extra performance out of your bike.

 

2-1 & 2-1-2 pipes will always make more power. Its fluid dynamics 101.
