b18c inside

I'm needing an answer to the cat problem that i'm having. What cat can i use? I did the swap in a 98 Civic EX. The bolt holes on my Civic's cat don't line up with the B18C's stock header flange. Please help me out. Thanks!!

yah use either a B16 or the B18c1 should work fine...

is there a difference between the b18c and the b16a cat? Are they both longer that the SOHC's cat?

its not really the size but where they postioned them, i think the cats are the same size but the stock one on lets say a D16Y7 is on the manifold where the B16a2 is further down on the exhaust.. but im pritty sure the 1.6L is the same but i think the 1.8L is just a tad bigger..
