I'm curious why you didn't go with the Power Duals. Just changing cams would not put your motor in the class required for the Hi-Output Duals and I'm really surprised V&H doesn't state that in their product description. Fuel Moto specifically states in the product description for their XXX Hi-Ouputs that they are designed for motors capable of 120+HP. Anyway, good luck in the future.

 

Had a similar problem with my 2014 CVO Limited 110TC, installed the 2/1/2 SS header with V&H 4.5" high output mufflers, totally lost bottom end, had to rev engine to 2200 to move away from stop. Been experimenting with baffles, mufflers and tuning (PV-2), going to try the E-Series next.
Good luck with your quest.

 

When they did my motor I was told with heads cams pistons throttle body changes we were making these were the pipes to go with....
I originally wanted power duals and monster ovals.
The V&H rep recommend stainlessential hi output duals...

Pretty obvious his recommendation was profit based only.

They have always blamed the problem on the tune. Three different tuners have looked at it... It's the pipes

Oh well lesson learned next pipes won't be V&H.

Beautiful pipes great quality.. But customer service is extremely lacking to say the least.
