Ferret, thanks for the reply! Unfortunately here in New York, my car has to use a CARB compliant cat, otherwise I would buy this one! Sellers don't even ship them here even if they're not CARB compliant :/

Hey guys, I need some help with my full exhaust setup. I am trying to make it bolt on in 3ish pieces: header, cats, and catback (2 pieces). I'm going bolt on to avoid any welding as I have a limited budget. My current exhaust is rusty and the previous owner replaced the flanged with pipes and added a welded in flexpipe which has failed with a gnarly crack/leak. What I'm buying: Inferno Fabrications single port uel header (2.25") OBX catback (2.25") made for the 1998-2001 Impreza RS. What I am looking to buy/have found: Aftermarket catalytic converter (1 piece) made to fit in 2.5L (1997-2005 Legacys, Foresters, Outbacks, and 2.5L Impreza's). Does anyone know the inlet/outlet diameter size of these catalytic converters or what size donuts or flanges to use? I've been searching on many forums (here,nasioc, rs25, and a few others) but can't seem to find an answer. Any input would be appreciated.
