just install a decat pipe from delkevic (UK) with the original muffler.
# better response at lower revs, less valve hit at lower revs
# too loud for me... probably if I had 20years old, I would enjoy the raw sound of the 2 ducati cilinders🤗🤗
# lost of torque at mid revs, removing the exhaust valve you lose back pressure, you don't notice if you rev from a 1st or a 2nd gear, but if you rev it, for exemple, a 4th gear. between the 4.000 rpm and the 7.000 rpm, you will notice lost of torque.
next tunning for this topic is:
# change the original muffler and put a 370 to 470mm oem muffler to:
- get that lost torque at mid revs
- decrease the loudness to something less agressive (and more bass on it).
I'll keep in touch
