Full exhaust system installation DIY (request)

alright soo I got everything on (fatty pipe, pro circuit silencer, 280 main jet) and there's something wrong. When I get the revs higher when I'm holding the throttle, it sounds like it starts breaking down, or like it's hitting the rev limiter too easily.

What adjustments should I try? I turned down the idle and that worked a bit better
 
just don't go through any deep water or anything and it'll be fine. it does have an airfilter right?
 
if you're not running it through deep mud or water, i wouldn't worry about it, it'll sound different too, be a little louder lol. you're just really rich with that fmf and the lid on. rip it around with the lid off and it should run better
