I know this will seem stupid to some but has anyone seen for sale small 3" diameter catalytic converter inserts that go inside long tube headers? its for a non f body project where ground clearance and emmisions are both a concern,

No such animal. Magnaflow spun metallic cats are about as small as you are going to get.

I heard ethanol doesnt put out emissions you can switch to that. like I said thats what I heard, I'm sure someone on here can elaborate more or correct me.

You can tune out the rear 02 sensors, or use 02 sims.

I had a set of Jet-Hot headers where the cats were
inserts to the Y-pipe (optionally, you could use the
hollow inner pipe sections also provided). But these
were not up in the header, per se. They occupied a
couple of short regions of expanded tube in the Y
(between segments).

They are probably the least durable cat style out there,
blower guys used to eat them up quick. Looked like
somebody just stuffed some Chore-Boy scrubbers up
the pipe segment, nothing robust about it.

Yes I know these do exist the question is where to get some? the ones you describe are made by JETHOT? not interested in tuning anything just not having unburnt gas smell exhaust....
