I have the '01 S/Cab, w/ a 5.4 L.

It looks like 2.5" pipe, past the Y, and 2.25" out the tailpipe/muffler.

Does this sound correct, or are they both 2.5" ???

Thanks, R1968

 

Should be 2.5 all the way back. Not for sure on a 01, but I'd think they would have kept the 2.5..............

 

Mitch,

Thanks for the info... As soon as I posted this, I had a break in work, so I ran out to the Truck. It does measure 2.5" at the tailpipe.

The Intermediate pipe does look a lil' larger, but will let the Muffler Shoppe worry about that one, when the time comes.

I tried to Delete this Post, but it will not let me for some reason. Is there something I am unaware of, when deleting a Posted Message?

Thanks,
