new pipe do i rejet

[sptrx300]

Hi everyone im thinkin bout buying a FMF megamax2 pipe but im not sure if i change the discs in the pipe that increase or decrease the power in the quad will i have to rejet my carb everytime i take a disc out or put it back in

u have to rejet when u first get the pipe. Also i do not think u have to rejet unless u change 6 or more discs. i could be wrong though
