Hello.
Just put it on and have fun. No other modifications needed.
To me it felt like it had a little more top end power.
But it might just have been the brutal noise that made me think it was more powerful.
To me it was too loud even with earplugs.
Racetrack use only, here in Germany.
Have a nice weekend.

I always had the baffle in and it was too loud.
After about a thousand km on the Nordschleife it became even louder.
Without the baffle it was really stupid. Did not ride it without the baffle.
I even tried the bigger baffle that is available to make it a little less noisy.
Did not make any difference.
Biggest advantage was the greater ground clearance and the reduced weight compared to the stock exhaust.
Now I'm back to the stock exhaust and everything is much more relaxed.
For Track Use Delkevic is fine.
On the road you would make a lot of people angry I would guess.
Hello.
Do you know "Fuel-Exhaust"? They are not so noisy. But i must say, i don´t even have one of it. It´s in Germany nor legal. But the finish and the price is very good.
