What is your question?
An engine is simply an air pump- get more air in, get more air out, and fuel to match.
So- every part of the system is a potential restriction- some maybe more so than others- but that can change at any time.
Not to confuse you- but for others following along- what I mean by that as example-the custom cams didn't gain much *at that time*- but that only means they weren't a large bottleneck- *at that time*.... so if I enlarge the ITB's and get a great gain- some of that may be due to already having better breathing cams, intake or exhaust in place...
There is no way to say a single part is worth a certain value- unless compared to an exact same configuration.
The Staintune muffler on a stock bike might be worth X- but if I were to test it compared to a stock muffler- right now- on my bike with the other mods- it will likely make a bigger difference.
