oh and try not to flame me lol, i didnt cold rev it or take off on it, i just let it idle and figured something obviously wasnt right, and this is my first exhaust...

the thing where the bung is, looks like it has to do with the fuel pump... and i just disconnected it from the exhaust before i took the stock one off, is there something im suppose to do with that? my mods are...intake gut and headers.

That's the exhause valve and there's a write up ( I believe ) in the "How to" section that will answer how to get the FI light to stop. Other than the blink, there's nothing wrong with your bike.

I'm not sure on this for the '08 ( newest bike I have is '07) but '07 and down... Only Cali models have an O2 sensor.

but yes, youll want to put an O2 sensor in that bung thingy. Can't let it go to waste! Arrow headers + Bazzaz AFM ftw.
