Because it’s a special kind of toxic. I’ve never seen people’s eyes roll back in their head or them stumble away from the toxic cloud of nasty lung burning invisible death that comes from my 850 when we are doing a pin and wiggle to get unstuck. I’ve forgot to mention this on the forum for a long time but the 850 Doo exhaust is somehow WAY more nasty than even an 800 ETEC. ALL the 850s in our group blow the same invisible toxic death gas. What gives lol?
