alright so will a fmf header give a good power increase over stock my dad thinks it wont give it any more power than stock and i want to prove him wrong so will it give it more power than stock
besides porting and a head mod, most aftermarket pipes are considered the most bang for the buck.
and yes...the fmf is a huge improvement over stock when jetted correctly for the new flow the pipe provides. as any mod to flow requires
what i'm seeing here in the pipe shootout, the fmf gold series showed almost a 2 hp. gain up thru the rpm's, and spread the power out over a greater rpm range over the stock pipe................
