Message	It's not simply a matter of size it's very important to pay attention to the profile of the barrel. By machining a smooth transitioning taper on the 54mm stockers I came within 4% of the 58s which are ~7% larger. I gained over 33% airflow over stock which is an 8% difference in size. The 58s gain 38% airflow over stock with a 16% increase in bore size. If the 62s went up to a 2 3/4" coupler I could add a nice taper to them and you'd see close to the 63mm Stanzas but I like the idea of being able to retain your existing couplers for 2.5" IC piping.
