Are the megaphone tips on a header better, worse or no difference than say a straight collector or even a reducing collector size? By reducing i mean it could be 5"or whatever and taper down to say a 4" or even a 3.5" or 3". Also how would these different tips affect things such as scavenging or backpressure? Thanks and you do amazing work.

If you are refering to what is commonly called a "reverse Cone", you got me. And a couple of years ago I asked Burns what they do and I forget the response...
Interestingly enough they have always made them a inch smaller than the max diameter of the megaphone. So there are no answers from me... Ha.

Hey Calvin...or anyone else...does the firing order matter in a 4-2-1 header?
