Why has the fuel economy decreased on my machine after installing your exhaust?

Why has the fuel economy decreased on my machine after installing your exhaust?

Because the HMF exhaust systems increase the potential air flow through your engine that must be compensated for with more fuel.  In order to maintain a safe air-fuel ratio when flowing more air through an engine the fuel flow has to increase roughly the same percent as the air flow.  If your machine develops 10-15% more power it will need at least that much more fuel.
