You need to do the following free mods at a bare minimum.
BK Mod (limits pump duration squirt)
Remove the exhaust insert and use a PMB or equivalent or better yet, get a new silencer
Remove the airbox lid
Advance the cam timing to YZ
Pull the grey wire
Make sure the throttle stop is cut similar to a YZ
With these mods, you should be able to hang right with a KTM 450.

Throw this pipe away and replace it with a stock YZ pipe, a FMF Power core 4 with a Q modular insert or a FMF Q. Either way, your bike will loose 3 pounds and give you at least 2 additionial HP all across the powerband.
I'm not sure you need to do the throttle stop.... canadian bikes don't need to have their throttle stop modified. Same with the grey wire. Just chek before trying to do these two mods.
Don't worry about your 426, you'll catch that pumpin soon.
