There was a press release from Abarth, in Italian, in the middle of May re the accessories. It also mentioned something about Blue & Me with telemetry (I thought that was already out unless it's something additional). A portion of the press releaseit, translated by Google, says:
"Obviously, the public can also enjoy other accessories such as seats "Abarth Racing powered by Sabelt and unloading of a" dual mode "back to the variable that can enhance the" sound "of the engine above 4000 rpm . These contents, mounted on the Grande Punto Abarth SuperSport, will soon be available for all Abarth."
So, perhaps, the exhaust will also be available for the 500
