Im thinking of picking up a hotbodies megaphone for my bike.
Other than a k&n air filter, the bike is stock. This unit replaces the muffler and cat.
I know that Optimal performance would be reached with a PC and dyno tune, but is it absolutely necessary to run a different fuel map?
Will I actually cause damage buy just installing it and not changing anything else? I have heard mixed info on this and just want other opinions. Thanks
