Catalytic Converter Rattle Sound

[chrisis]

i had the rattling noise for a year now and yesterday it was really loud so i checked it out and the noise is coming from the cat converter.

i have a 96 with almost 140000 miles and no check engine.

i'm thinking to get another one like Dynomax etc.

what you think keep till it trickers the check engine light or replace it?

maybe its just all rusty and thats the rattle? mine looks horrible, mine doesnt work tho, haha, personally if u dont mind the noise id keep it unless u got the extra money for a new one... good luck
