Looks like the exhaust on my crx is finally done and the cat doesn't look much better. Figure I might as well replace both of them. I plan on getting a classic thermal catback and have KTeller put flanges on a carsound cat.

My question is, what size catalytic converter should i get? I believe the Thermal is 2.25in but what is the stock crx header? I am pretty sure the 2.25 will fit but I want to be positive before i order it.

 

I can't answer your question, but I do have a picture that may help.

From my 90 SI (picture is big :


NOTE: See how small that thing is ?!?!?!!

Anyone else have any idea?

 

one and a half!?! that stinks

 

Has anyone ever gotten a high flow cat with a stock header? I really need to find out so I can order this bad boy before the next autox.

 

^ look at new picture, i don't see why a 2.25" cat won't work
