Just got my bike back from the dyno and thought I would post my results.

Bike: 06 FXSTI
Pipes: V&H Big Radius
Intake: K&N Kit #3909

HP: 74.02
TQ: 77.83

Did a search for Dyno Results and found that I'm in the ball park with everyone else. Of course I Know that I could have got better results with different pipes but the sound that I get outta these pipes is sweet.

 

Those numbers are almost identical to mine. I am probably losing alittle with my pipes as well, but they will do for now. I may go to a 2 into 1 system next, but not for a while.

 

Numbers look good. I agree on the sound of the pipes, you should hear 'em without baffles.
