I wish I knew but the bike was upgraded at purchase. Need to compare with another bike. The tubes are all stainless and comes in two parts with polished double wall slip joint with arrow springs. Nothing sounds as crazy stock as the panigale however, especially at lower rpms.
Homologated inox silencer with black tips, Mv Corse logo impressed and exhaust valve. With the same shape of oem component that equipped the 2013 model, can be fixed also on all other F4 starting from 2010 model (in that case the plate holder is different).
I promise to tell the truth, nothing but so help me _(insert your idol here)__. I have about 355 at the moment. I forget exactly but its within 10 miles of this reading. Yes I just did change my oil (so fun ) but did not make a mental note down to the mile on the odo but its very close to 355. Now I am good to go to about 3K miles but will probably service again at 2K miles to finish off the running in of this baby, this beast, this beauty...kissy kissy..squeak squeak.
