I have a 2014 CVO Road King and am researching and reading like crazy to decide which V & H mufflers to go if I also do the Power Duals. I almost pulled the trigger on the Hi-Outputs but then read some posts saying they are too "wide open" even on a 110 and decrease performance/power. Some recommended Monster Rounds. Opinions? Dyno numbers? Recommendations? Experiences? Thanks!

 

I'm also interested in any feedback on Power Duals with Monster Rounds.

 

I have a set of the Monster Rounds with stock headers (no cat) and I am happy with them. I will someday put some headers on but for now I'm happy. The quality of these are great, sound is deep but mellow.

 

Do you know the baffle diameter on your Monster Rounds? I can't find it online.

 

I have the VH Power duel with the monster rounds .on a 2013 CVO Road King with the 110 very happy with the performance and the sound .

 

Thanks for the feedback. It's helpful to hear from someone with the same engine that I have. How would you characterize the sound and what seems different about the performance from stock?

 

I have the Monster Rounds with the Fuel Moto pipe and love the combo. The monster Rounds are a proven performer. I really like the looks of the HO's but haveheard the same thing about them. I am at 89hp/105tq with my current combo.

 

PD's amd MR's here. I like the combo fine. No dyno done, but the butt dyno sure feels an improvement.
Sound about right to me. not to loud, and a nice deep tone.

 

My buddy has the V&H power duals with monster rounds. Very deep, low rumble. Not very loud.

 

I am not sure what diameter they are off the top of my head. I would have to remove them and measure to find out for sure.
