CAT -- you didn't give year, make, model, your location

Hi Andrew,

Sorry for the delay.  I had to look up the company.  They don't do custom as
I said;  however, if they don't have a replacement for your car, they'll
remanufacture the one you have.

The company is:  Marvin Miller Catalytic Converters
                 3295 Depot Rd, Hayward, CA  94545
                 800-826-6615 or 510-783-2212

I'm copying the list in case someone wants to put this in the Marketplace so
others can use it.

HTH.

Cheers!

Jim Jordan
