ok this got my interest so i just went out and crawled under to have a look. i got to wondering about the y-pipe replacement. when i looked under i see 2 precats then drops down and goes into the resonator/2nd cat (number 98) after it comes out there is a o2 sensor, then takes a short pipe to the muffler (which in my case is stock and new by the way thanks to ford dealership from previous owner) then goes into tailpipe #54171 which has this thing (which i dont know what it is) that is a step up in size and then back down before going over the axel.
now if i get the "random tech" y-pipe will i throw a CEL? i dont see a place for o2 sensor so im thinking it will. second thing is i going replace the stock muffler (do i have a restriction on muffler size) and probably leave stock tailpipe from there back...but what is this thing in the #84171 pipe? also is there a "CEL" resistor for the o2 sensor to keep it from throwing a CEL.
thanks for the help.
