I have been hearing that the Vance and Hines dresser duals and the Hi Output slip ons cause a loss of low end torque but really sound great. Is this a loss from stock even after getting the bike tuned? Or will it have more torque than stock but just less than the power duals? Or will I have to go with the power duals to get the same or more torque than stock? I really do not need more power than stock. I just don't like the quiet sewing machine sound of stock. However I don't want to have less power than stock. I would have thought a tuned bike would have more power than stock regardless of which header pipe is used.
The Vance and Hines Hi-Output have a torque dip in the low RPM, below 3000. It is most noticable dip between 2000 and 2500 RPM. They just do not have enough back pressure to make good low end torque. The 110 motor is very sensitive to the head pipe and mufflers, more than one tuner and porter has told me that. That said, their are not many if any that have a better deep sound than they do.
You would need to add the power duals to get rid of the cat and a tune to help make up for the torque dip.
Me, once I saw the torque dip or loss, I changed to a fullsac baffle in the stock muffler.
I still have the hi out puts, love the sound, but wanted the torque more.
For me, on my CVO Road glide, its just a tune, Fuelmoto Jackpot head pipe, and Jackpot pro tour mufflers, its my traveling bike.
My king, Stock was not enough power. I have done a little bit of motor work, see my signature, 121 HP and 121 Torque. The torque is over 110 at 2700 RPM. A long torque curve that does not start to fall from 120 until 5000 RPM. Makes my 12 CVO road glide feel week. A blast to ride
