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
 
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
