Few weeks back I was asking about noise from cat converter. Steve was right on the money when he said, "old cats can do that". Anyway, I took cat off to find busted up pieces of asbestos, refractory or whatever the medium is made of and hollowed out the cat. Didn't feel like droping more big bucks so I am re-using the old one. Holy crap, what an increase in performance!!! :yup:
