I went to autozone and purchase the 1994 Acura Legend gasket and it came in two pieces? Appararently this gasket will fit with the 2.5 collector and itr header? My question is would this work because it doesn't look anything like the real jdm donut gasket.

 

Are they 2 steel rings about 2" in diameter? You may have gotten the gaskets that goes between the manifold and the A pipe. What you need is the one that goes inbetween the A pipe and Cat. Here's the Honda P/N (I think it may be an Acura only part though): 18229-PCX-003
