I got an email back from Magnaflow about a question I had as to whether or not they had any direct fit or universal high-flow cats with 2.25" in/out for my 96 EX coupe.

The rep said they had a universal model number 91035, with a 2.25" in/out, but the bung for the O2 sensor was at the end and not in the centre which he said he believes I need.

Does anyone know if this would work for my car? Anyone have any model numbers for HF cats that would work for a 96 Si?

Thanks.
