the exhaust ports are seperate 2-1 and 2-1, meaning 2 of the ports share one outlet to the cat convertor, better air flow. instead of those g@yyer ones that they've replaced it with, where all the ports share one outlet to the cat convertor. which are the ones where the mani is welded on with the cat convertor.
