new to here, just got a 2016 580-2...
is the exhaust configuration or mounting same as for 610-4 ? i'm asking cause I've been told by the salesman that the 580 rear is slightly different ... the exhaust sticks out a bit more as well...

I want to get rid of the factory exhaust but hoping I can choose from the existing 610-4 exhausts that are out there...

would be nice to have a valved exh. but can be opened to super loud/almost straight/race if on 'open mode'.... i.e. in the sport and corsa ?

please advise,

james R
