Piston

anyone here tried the 57mm mtrt piston. what is the difference between vixion piston and mtrt piston. im planning to replace only the piston of my vixion kit. is there any tweak to do or just plug n play? is it also ready for stage 2 cam coz the piston is already pocketed? and the performance between the two. vixion piston and mtrt piston.
