Please sell me your catalyst!

Mine rusted out (124.131), I decided to kludge together an aftermarket catalyst rather than pay $1600 or more for a star-marked part from the dealer. My entire exhaust system had holes, so now I've got all aftermarket parts in there, and they do a terrible job of keeping the engine noise down. The car really sounds like it has an exhaust leak, but neither I nor my Indy could find one, so I blame the non-factory exhaust system.

While trying to decide on a solution, I drove the car for several months with no cat. I could not detect any increase in power or MPG. MB put some work into designing these, keep the cat and be happy.
