What high-flow cat did you use?

I was hoping to get some idea of what cat's other people have used.

I bought a universal Magnaflow cat and was in the process of installing it on my 1996 Si coupe yesterday. The size and length are perfect but.... the O2 sensor location is on the wrong side, and it's on the wrong angle.... Ooops.

Any details of cats that you have used would be great!
