thats what i was thinking ...i mean the dyn053 looks like a carbon copy of the 2053 grp ....so does the efra rating mean that the internals are different ....i mean the grp pipe looks nice and shinny ..but i mean the dyn053 hard coated looks infinitely more durable ....im gonna at least try it ...i mean how much less fuel mileage could i get .....????
