LRD 425 power up kit or a 450r

[WhiteBros400ex]

Should i get a lrd full system pipe and a lrd 425 power up kit and elka triple rate shocks in the front on +2 burgard a arms, rpm axle, elka back shock or get a 450 and get a lrd pipe and 11:1 je piston. Which would have more power and be better or would it be more ridder just looking on what people have to say i have my mind set or a 450 and am about to trade my quad in this week.
NE ideas:)

if you can get all those mods, i would pick all that over the 450r!!!

Yea i can get the mods but will it be anything to a 450 and how much power increase does it have.
