Just did this to my 2014 Cali. No exhaust mods yet, my h pipe has been welded. I’m a one year owner of the two owner bike. It’s old, yes, fixed some issues via the forum here, then installed the fuel system mods, and I can say it truly is night and day. I don’t like loud sharp exhaust, and I ride two up on this, and Canada dollar and taxes bring the pretty, full exhaust knocking on 4000 dollars. That is my largest problem getting the exhaust, because with no dealers present within 6-7 hours, I would have to keep this forever. I may end up doing that anyway, and if I do I’ll likely get the header set up to avoid other exhaust issues. Great site, contributors and products! Found my new bike to love.
