Insertable cats I have seen catalytic convertors that get inserted into a 3" pipe instead of being welded/clamped to the pipe. However, I cannot fid them anywhere. Does anyone know where to find such a thing?
I think Hooker offers them with their y-pipe to make it a "catted" y-pipe. I don't think that would pass a visual inspection because they don't look like cats, but as long as the tailpipe emission's pass I guess the visual doesn't matter. If you do put those in, I would take some pictures to prove they're in the exhaust in case they don't believe you.
My Jet-Hot Y has these. But I think they're kind of a joke
(little wire-ball is going to scrub the exhaust like a full brick?)
and they don't even look like cats from the outside. And
more than one person has burnt right through theirs.
FLP (?) I think made headers / Y where the cats were
flanged and a straight piece was also provided, this is a
clean way to go and any exhaust shop could flange you
a pair of cats and a pair of identical tubes. Flanges cost
a little clearance but maybe can go wherever you have
some.

I don't have to worry about visual inspection or emissions. Actually, my main concern is Db (loudness) of the exhaust here. Does anyone sell these seperately from a y-pipe?
That aside, those in-pipe cats are crap. The reduced surface area raises back pressure and therefor robs more power than a normal cat. Just get a set of the bullet style cats. They flow good and the small size only minimally effects ground clearance.
