why don't you just run that kit but not install the y pipe and run your true duals from there?

 

yeah cut it off at the Y and install your X-pipe there

 

do you still have these? if you do will they fit my 2002 f150 5.4 with true dual's?

 

nah theyre on my truck and have been for quite a while

 

ok, so did they give much of an increase in power or sound, im looking for some headers since my manifold is leaking

 

Will these work on a 2000 F-150 4.6ltr motor
