Exhaust mod

I had to test my resonance theory, my idea was that the noise came from a too short exhaust pipe and a worn out muffler. The muffler was also a "pyramid" and therefore was working as a noice enhancer instead now when all the wool was gone. So I bought a new "flow through" muffler to get a longer exhaust. Of course, it was too long and I had to cut it down and custom build the end pipe. I think that even if this one also is blown, the resonance will be kept away because the flow through design.

Result: Noise improved! :)

Now I can do some hard acceleration before there's any noise and when high speed cruising the noise is totally gone.
