Have 2011 Road Glide Ultra that I want to do an exhaust upgrade on. All I am wanting to do is replace the header pipe to get rid of the heat from the cat and richen it up a little to get rid of the pinging. I'm happy with the current, stock power. I don't need 500 hp to ride the cruise at 70 mph. And I want to keep it as quiet as possible and I want true duals. I am leaning towards Vance & Hines dresser duals cause I like their looks and run my stock slip-ons. Then, either do a PCV install or a dealer dyno. Anybody see a problem with this? Any suggestions? Thanks
