Hey when did harley start putting cats in there exhaust,also,
did they first put the cats in the mufflers and then later the
head pipes?
Hey at least it isn't a thread about gutting the pipes or Will
my bike run cooler if I gut the dang thing
Softails started in 2010 in the muffler. Not sure what year but I think the baggers started off in the head pipe.
Pretty sure the last carbed bikes in the 90's had cats in California only...I have a mag where they cut one open to see what was in it ...after they couldn't get any air to flow though it on a flow bench.
