Hello everyone. My stock catalyic converter needs to be replaced. However I'm looking for any suggestions as to what may slightly improve sound and/or performance, if any, with my 3" cattman exhaust. Should I stick to stock since some posts feel that cats don't do too much. Or do I get something high performance like a random tech (have read very average posts on it). Any suggestions greatly appreciated.

I read the stock cat actually flows better than the Random Technology HFC. Go with either a test pipe or Cattman FastCat...you won't really notice a huge difference unless your cat is clogged, it'll be mostly difference in sound and that's only if you have headers.
