Help me find the right catalytic converter (please)
my stock EX cat mounted up perfect with my mugen header (2.5 collector) correct me if I'm wrong, then to my apex WS catback for a 99-00 si. It needs to be 2 bolt flange at the header, then 3 bolt where it connects to the exhaust. Please help me find the correct one to purchase. All suggestions considered.
thanks guys
Where's a good place to buy?

Re: Help me find the right catalytic converter (Stillmatic22)
IIRC the OEM ex/si cat is the same. Are you looking for OEM spec, or want to upgrade? I think the easiest way is to get a magnaflow Carsound cat that's 2.25 In and out and have a muffler shop weld on a new 3 hole flange and if possible re-use the flared flange from your original cat.

Re: (Deemeetree)
If your stock cat mounted "perfectly" to a header with a 2.5" collector something is wrong.
Here is a photo of a stock civic sir cat next to a jdm itr cat which bolts to a 2.5" collector.
