as a few of u know im downsizing from 60mm pipes to 50mm pipes,mainly in hope of fitting me fogs,plus 60mm seems to be putting bumper understrain and pushing it off.
but the hoses i have are 51mm,but say 50mm on them,so u cant get 50mm exact its either 50.8mm or 48mm diameter. maybe 50.8mm on 50mm hose maybe a bit tight?
but will 48mm diameter be ok flow wise im meaning,was thinking it may be a bit constrictive?
btw looking at the heat issue that may be caused(if any) by smaller pipes
