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
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.
