I know you said you don't have a ton of money but.......
I have a brand new Boss Noss setup for a Vector that I just bought and then my sled got stolen. I can make you a pretty good deal on it if you are interested. Shoot me a PM if if are interested, I'm leaving town for a 10 day riding trip this morning as soon as everybody gets ther a$$es out of bed so I won't likely get back to you right away.
As for the Vector follow Kachess's $6500.00 mountain animal thread as most of the mods apply to the Vector as well. Don't mess with the Vector airbox though. Do the exhaust, battery, rider forward, hood/headlight then look for a skid, then get some other lightweight stuff like a front end (I have a light weight front end for sale as well).
Try and find a 151/16 2 1/8" track from like a 06 Rev for it if you want to build a boondocker. Vector doesn't really have the power stock to climb too much. I had the Excell high flow header with a glass pack under the tunnel which worked well and dropped like 18 lbs.
