I've been reading and that seems to be the best way to go to get auto decompression. But should I purchase a cam for a certain year model YZ450?

You have come to the right place. There is more on the topic you mention than you may ever care to read. See: http://www.thumperta...078#post3706078

I have done the Mod with some help and the mod is hands down the best mod that can be done on a 426. CAM you need is an 03 450 OEM Exhaust. Read on!

'03-'05 would be my first recommendation, with the '06 just after that. But unless you get a deal on the OEM cams, they are not as advantageous as they once were. Read:
