after market exhaust FZ6 help

[Yammi]

Hi all just got a 07 fz6 and looking at fitting some  after market exhaust but i have some questions

I have a mate who said if i fit an after market exhaust to the bike then the bike is not going to run right ?

he said i would need to get a power commander for the bike to run right because the ecu is set up for the oem exhaust

and not the  after market exhaust  :groan can some one help me please

  I am also presuming that if I do change the exhaust, etc. it will need tuned to cope with the changes, is this true ???

All help greatly appreciated and cheers very much in advance..........












I fitted scorpion cans about three years ago, and the bike runs like a dream.  I was advised at the time that they fit straight on the bike with no remapping required or tuning.  Hope this helps.
