My friend owned a shop that had a dyno-jet dyno in it and I was fortunate in that he let me use it a bunch over a couple of years and even invited me down when they had dyno-jet in to do a school. I got to see & experience a lot of different things.
On the slip ons I have the Delkevic 18Ē carbon fibers & quite frankly other than the sound canít tell any difference but I learned that the ďbuttĒ dyno is a really big liar ! 99% of all Aftermarket exhaust actually makes less h-power than the factory stuff and the really good stuff makes about the same or maybe 1-2h-power more. Thatís it ! The big performance gains are the fact that the aftermarket stuff usually weighs significantly less and thatís where they give you more performance. On my 80 cbx one of the oe mufflers weighs as much as the entire 6-1 header for an example.
All the bikes I seen on the dyno from the factory actually were setup pretty rich which is why most header companies will tell you no rejetting is required, Iíd bet the fjr is the same. So if you like the louder sound (the fjr has a very nice deep bass rumble!) and the money to buy enjoy! But there ainít no more performance other than in your brain, itís the. Harley effect, itís loud so it has to be fast !
