A notible increase in horsepower, based on the 2005 H-D Roadking dyno testing, showed a great boost of power. They will make your bike sound the way a Harley should, deep and throaty. You can feel the seat-of-the-pants performance as soon as you crank it up and take a ride on the motorcycle.

”Our DYNO tests have shown these increases, but every bike is unique according to what pipes and modifications you currently have”. So results may vary and with the testing that was done on the 2005 and there was no need to re-map the computer. The only modifications that were done were the slip-on Full Boar mufflers.
Starting with Stock pipes, we ran the bike through the Dyno. The results came in at Baseline with stock mufflers —no other modifications.
