Sounds like you enjoy tinkering and thats what the hobby is about. If I were you and money was available Id buy a good quality set of headers power output appropriate and install them with true dual exhaust and nice turbo mufflers. Dont do it in the chase for improved performance but do it for great sound and enjoyment. If you dont have the $$ for headers do a true dual exhaust with existing manifolds.


Keep old mopars alive.
