I went with the Rinehart Extreme true duals for my 10 FLHX. Certainly not the cheapest pipe on the market but I love em. Have a nice rumble to them when you're just cruising and then when you get on it a little, they get loud pretty quickly. I had the Vance and Hines Big Radius 2-into-2 on my 07 Fatboy and loved them. Vance and hines pipes are a little easier on the wallet.

Good luck!

 

Put V&H header pipe on my FLHTK and the fuel moto Jackpot slipons. Great sound and great performance. Not too loud idle and really sounds good when you get on it. GOt the complete kit from fuel moto and very satisfied. Over 8K on the system since I installed. Had loss of power from the cat onthe stock pipe. Now plenty of power!
