the OP was asking specifically a comparison on the JDL 4-2-1 and the ACE 350 headers. if the price difference was worth it essentially as the 350 is a bit more expensive.
but yes they do achieve their 4-2-1 "Status" differently, as the ACE utilizes the overpipe which seems to be a better more effective way of maximizing mid range while still being able to substantially increase top end.
