ok, the other post wasnt what i wanted. i really need help ordering a high flow cat. going to order from kteller.com, but i need help figuring out what size im going to need!!

right now i have a 92 Si hatch with a JDM B16 with stock mani/collector. i was told the collector size is 2" on that. then i have, for now, a stock cat from the car and i have that bolted to a cat back Apexi WS2 exhaust. the size on this is 60mm (2.36")

so what size do i need?? will a 2"in and 2.25" out work?

TIA

 

please im ordering tomorrow and dont really want to use an ebay brande "high flow cat"

 

im not sure how the emissions are there but we have none here and NO one runs cats . its a little louder but im sure its good for a couple HP

 

i know that, we got no emmisions here in canada either, i dont want a test pipe tho cause i want to keep it quite. i think a high flow cat would be better than my stock one

 

up for going home to bed

 

bump, back to work

 

2.25 in 2.25 out.

 

all flanges should be universal. the only reason you should be worried about the in/out size if you dont your exhasut to be restricted, which it will be from a high flow cat.

 

oh ya, and btw. i have a ws2 with my b16 and i have a "ebay cat" and its not loud at all. Just get an ebay cat they all do the same thing.

i thought the point of a "high flow" cat was to increase the flow IE-less restriction than OEM cat

what kind of "ebay" one do u have on there now? can u find a link?
