i was told by the shop today that the 07 and 08 aliehaeds are not the same. according to the shop manager he says he has talked to brock directly and that the 07 pipe will fit but will not produce the power that the 08 pipe will. does the head flow differently than the 07 head? are the headers bigger to accomidate more air flow? what gives? thanks
