I purchased a 84 CJ7 about a year ago. It has been converted to a 304 V8. Why the guy didn't go ahead and put headers on then, I don't know. Anyhow, I need to replace one of the mufflers. I will be having new duals ran and want to know the best mufflers to use to still get a little noise. Give an idea on muffler cost as well. I don't want to break the bank. Thanks folks!
