Will this cat fit on a b16 header? Are all the donut flanges on these cats the same size or different?



Thanks

i am using my stock 91 CRX DX catalytic on my car with a b16 and a factory header. i believe the fartory b series header collector is about 2.0" - 2.1" in diameter.

Thanks very much


So that donut flange is the same for both B and D and fit aftermarket headers too?

thanks

if it fits on the exhaust it's for it.... there's no such thing as a "d-series/b-series" cat

 

What does that mean? So a cat from a Type R is the same as a cat from a 88 crx si with a d16?

Is the donut flange the same size for both? Don't think about the answer too much guys...just post if you know all these D or B cats have the same size donut flange size or not.

I don't have anything with me to test out so just going by pictures right now.

well I bought a crx si donut gasket and it fit fine on my US type R header. so it should be fine

 

It should work but I know some of the older headers have the head flange on reversed, so you have to rotate the cat 180 degres, this would cause problems with the flange on the back side.

 

Ok thanks guys for the info
