Need O2 sensor P/N

[Azplinker]

Well, I can't tell how to remove a liner if it has one. Is there some illustration that you have access to that would help me determine where the liner is located and how to remove it? The TSB only shows the downpipe with a small bolted-on heat shield on the outside.

its long gone, (sorry no photos. most went bad 20 years ago, and nobody felt like photo'ing then..., lost in the sands of time, with only 1 TSB as a clue)
please be aware all this oddness, is EPA required, anti smog devices, it's runs red hot and burns up gas while a dead cold cat is present, at cold engine start.
it's weak design and idea..., and loves to melt and blow out (crack,split. and self destruct too)
others see it there, (saw it log ago) and just rip it out, what was left or blocking paths. if blocking the exhaust.
if pipe does its job, let it be. (unless $300 new pipe from suzuki is in the cards)

i made a new table, called unified, all we need now is just one table, I HOPE !

I'm hoping it covers all 10 years, !

in fact , i think yours is the TSB upgraded header.
if it looks like all the metal inside is TOUGH , then it is. newer upgrade..
