Slow to ship by today's standards (5th business day, also the day after I emailed asking about it) & fitment issues on Honda Rubicon 500 (melts plastic footwell panel). Fitment issue needs to be addressed during manufacturing to clock the muffler inlet pipe so is further inboard toward quad centerline & closer to the chassis to create an air gap between the exhaust tubing & plastic panel. Header can be clocked during install, muffler can not.
