nice one man, corey dont listen to these guys, its good that someone is getting their own opinion on the pipes and not take the advice of a person telling you what to do, and one more, how was the yoshi sound wise, was it quiet?? cause i found 1 and i need a new zorst and it needs to be quiet.
thnx and good luck with your next pipe escapades, keep us posted

well, Corey to construct a exhaust is a very complex thing to do.....you can use a very short formula:
Long pipe = little peak power and much torque out below
Short Pipe = much peak power and low bottom torque
Large diameter = much peak power and low bottom torque
Small diameter = low peak power and much torque out below
...but there are various other things to consider ...like cam timing ,overlap, intake length, temperatur of the exhaustgas, desired powerange......etc!!
So...splitting a cheapo exhaust in half and hope it will fly won´t cut it

mountain are you able to provide more specific equations, or point me in the right direction to find them

sorry but if I had a program or a formula (like for twosmokes)to do so ,I would be a rich men ...unfortunately its more try and error....a lot of acustic phisics helps but only a bit

one thing I found is:
(r.p.m) (depressions/cycle)
f=---------------------
(2revs./cycle) (60 sec/min)

to determine the operating frequencey for a given engine speed ...its part of a patent which can you find here:Patent Login
and here:
Patent Login

and this is interesting too:
Simulation of gas exchange of two- and four stroke engines. Applied software. Internal combustion engine department. BMSTU.
