This..

As far as gains are concerned I'm sure the plog/downpipe combo flow pretty good compare to headers.. Most probably won't notice the difference on the butt dyno. Price wise well if your buying both new headers are the better choice. Like everything it just depends on how must you want to spend and sometimes leaving good enough as good enough.
