I would say save ur money ... catch can looks cool but if you're not going to race ur car and run it in harsh conditions under high rpms then not worth it ...
Scott will say different than I would ... I just know this from racing enthusiasts who have mentioned that a catch can is not needed ... I mean Irf do you race ur car all the time ? do you rally ? if not than no you don't need it
I would make the investment. The amount of oil it catches is amazing (on the 6.1). I'd hate to think I'm spending extra on 93 and this oil is mixing in lowering my octane rating and the engine NANNY is pulling timing.
