I see no differance in fuel milage and if there is any power or perfomance boost i cant tell. people talk about it whiseling but i dont here anything differant. That could be do to the fact I have 5" exhaust and it whistels already. I will give it a little longer too see if I notice any changes befor I remove it from my truck.
