440ex with 450r carb

[djwilliams0822]

I have a 440ex2001 it has a unit filter and stock exhaust. I am wanting to get a 450r440ex2001 carb on it but with it having stock exhaust will it make that much more of a difference? Or should I put a slip on on it instead?

it will still make a diff but id get a slip on first to kinda complement it jmho
