Mine appears to have had a carbon one with small outlet holes with the standard system and a carbon one with large holes for the Termi, it's a 2003 Fila though so maybe different - bought off the original owner with all the bits present showing 1500 miles. Bike is standard with no mods.
That picture is from the original spec sheet when they were introduced so maybe yours didn come with it . But in 2003 thats how they were advertised.
Never ceases to astonish me as to why people continually try to associate Rossi with their Ducati’s, do they not remember how brilliant he was the 2 years spent in red!!!!
