Pure 1 oil filter IS missing the bypass valve, take one apart if you don't beleive it (it's a little themostatic spring I think).
Elevated ZDDC in RedLine oil does burn up (eventually) the cat; but it also provides the extra protection that later oils (1998'ish - present) do not so it's worth it to me...
