Simply pull the stock slipons off and knock out the washer inside the tube on the end closest the catalytic converter. Better low and mid-range power with no ill effects noted. Results in a low rumble at idle and a quiet growl on acceleration that is overcome by the noise of the wind at about 60 mph. Way better than stock without being obnoxious! Result!!!
Well, I believe you, that it's louder. However, as the stock exhaust is optimized for the EFI, I wouldn't think, your modification enhanced any power, rather it jeopardized the overall well designed powerdelivery.
Unless you provided real numbers of a dyno run, I guess, that's just wishful thinking. May be, it "sounds" more powerful...

99% agreed, and I am not German.
The 1% of discrepancy is that I am sure that the original exhaust has been optimised, but the optimising criteria is always a trade-off of different factors and these might not be the same for everyone.
It's about the right trade-off between max power output, power delivery (driveability), noise, emissions, efficiency... and you can't be the best at all of them at the same time.
However, I will stay with what Honda has decided is best for this bike
