Hey all,

I've been told that the Geo Metro's have an exhaust design flaw in which the exhaust gases don't expel properly, causing the head to overheat and all sorts of problems. They said a larger muffler would solve this problem. What have you all heard (if anything) about this, or is it myth? Thanks.
