I wouldn't loose too much sleep over those wierd exhaust pipes. Didn't we see something like this on the 1M mules? Or maybe I am just remembering those cold start videos we saw from the "lucky 12" test day(s).
What I find
more interesting is this is one of the first M2 mules with
production front fenders and not the velcro'd add on M235iRacing fenders. The M2 is really taking shape!
