pls confirm if there is anytthing at all inside the precats
the last time i brought this up it was 50/50 who said yes there is an obstruction inside the pre-cats.
on my old 3.8L, my 5.8L and my 5.0L, after gutting the CAT, i ran a wire up inside the exhaust and ran into no obstruction all the way up to through the header.
anyone?
my 88 Sport was hollow (brother said he gutted them when he had it, IDK for sure). My buddy had an 87 and there was definitely honeycomb in them. He put my Y pipe on his after I swapped to an H pipe and we sold all three cats out of his Y pipe
ok,, thats 1 vote for "the pre cats are full"
Barring outside interference, the pre-cats will be full.
then i guess i better double check my 20th.
my oldest boys bird sport were empty, i spoke to the previous owner last week and he said he did not gut them.
good news for me if i find them full.
I've been told by a ler shop that they are resignators(sp?)
master ler charged me for three cats when I told them I had to pass on my old 86 and said all three were gummed up, so i don't know.
