Thanks for the clarity, Brian, and you're hilarious! Understand your point, have encountered exactly what you're referring to regarding fits. The "downside" might be familiarity of various pipes under the tech tent? Not all are stamped w/ part numbers, that's tougher to monitor. Then, the ever-present racers tugging at one's sleeve while pointing to a competitors pipe that doesn't look "right", increases anxiety. Not sure about you, but I cant go to a track anymore w/o a collection of new pipes as a reference.
