Level of Incompetence

So ya call the manufacturer; "yeah, hey dude, does your shorty drag pipes come with anti-reversion or torque cones"? "Ah, I dunno man, let me see if someone is around that can answer your question". Twenty minutes later, still listenin' to Muzak. Wutdafuck! Ya would think that a guy who works for a motorcycle exhaust pipe company would have an idea about gases other than the ones that come out his ass.
