This there any difference in SH model cats to the base model cats size.

 

I don't know if it's a different size. But i know that the SH has the cat in a different location than the Base Prelude.

How because of the header? On the Sh is the exhaust, cat or the header longer. I know that one is longer but which one?

 

I'm not 100% sure, but I believe that the SH header is shorter than the Base header. Therefore the cat is positioned closer to the engine block on the SH. And I would guess that the cat is the same. But again, not 100% sure...

Someone please correct me if I'm wrong...

im not 100% sure either but i strongly lean towards the SH having a longer exhaust
