Basically, bigger cams will make your engine have more power, but at a higher RPM. Same with extractors. Different length will give you gains at different RPMs.
So if you set your cam up to give peak power at 7000rpm for eg, then you want to get your extractors made to extract the exhaust most efficiently at 7000rpm. Add both those gains together = more power and a better power band.
